Welcome to Hyperbee Expressions\n\n`Hyperbee.Expressions` is a library for creating c# expression trees that extend the capabilities of standard expression \ntrees to handle asynchronous workflows and other language constructs.\n\n## Features\n\n* **Async Expressions**\n    * `AwaitExpression`: An expression that represents an await operation.\n    * `AsyncBlockExpression`: An expression that represents an asynchronous code block.\n\n* **Yield Expressions**\n    * `YieldExpression`: An expression that represents a yield return or break statement.\n    * `EnumerableBlockExpression`: An expression that represents an enumerable code block.\n\n* **Using Expression**\n    * `UsingExpression`: An expression that automatically disposes IDisposable resources.\n\n* **Looping Expressions**\n    * `WhileExpression`: An expression that represents a while loop.\n    * `ForExpression`: An expression that represents a for loop.\n    * `ForEachExpression`: An expression that represents a foreach loop.\n\n* **Other Expressions**\n    * `StringFormatExpression`: An expression that creates a string using a supplied format string and parameters.\n    * `ConfigurationExpression`: An expression that allows access to IConfiguration.\n    * `InjectExpression`: An expression that allows for depency inject from a IServiceProvider.\n    * `DebugExpression`: An expression that helps when debugging expression trees.\n\n* Supports Fast Expression Compiler (FEC) for improved performance.\n\n* Supports interpreted expression trees using `lambda.Compile(preferInterpretation: true)`. \n    ```csharp\n    var lambda = Expression.Lambda\u003cFunc\u003cint\u003e\u003e(Expression.Constant(1));\n    var interpetedLambda = lambda.Compile(preferInterpretation: true);\n    ```\n\n## Examples\n\n### Asynchronous Expressions\n\nThe following example demonstrates how to create an asynchronous expression tree.\n\nWhen the expression tree is compiled, the `AsyncBlockExpression` will auto-generate a state machine that executes \n`AwaitExpressions` in the block asynchronously.\n\n```csharp\n\npublic class Example\n{\n    public async Task ExampleAsync()\n    {\n        // Create an async block that calls async methods and assigns their results\n        var instance = Constant( this );\n        var result1 = Variable( typeof(int), \"result1\" );\n        var result2 = Variable( typeof(int), \"result2\" );\n\n        var asyncBlock = BlockAsync(\n            [result1, result2],\n            Assign( result1, Await(\n                Call( instance, nameof(FirstAsyncMethod), Type.EmptyTypes )\n            ) ),\n            Assign( result2, Await(\n                Call( instance, nameof(SecondAsyncMethod), Type.EmptyTypes, result1 )\n            ) )\n        );\n\n        // Compile and execute the async block\n        var lambda = Lambda\u003cFunc\u003cTask\u003cint\u003e\u003e\u003e( asyncBlock );\n        var compiledLambda = lambda.Compile();\n        var resultValue2 = await compiledLambda();\n\n        Console.WriteLine( $\"Second async method result: {resultValue2}\" );\n    }\n\n    public static async Task\u003cint\u003e FirstAsyncMethod()\n    {\n        await Task.Delay( 1000 ); // Simulate async work\n        return 42; // Example result\n    }\n\n    public static async Task\u003cint\u003e SecondAsyncMethod( int value )\n    {\n        await Task.Delay( 1000 ); // Simulate async work\n        return value * 2; // Example result\n    }\n}\n```\n\n### Yield Expressions\n\nThe following example demonstrates how to create a yield expression tree.\n\nWhen the expression tree is compiled, the `EnumerableBlockExpression` will auto-generate a state machine that executes\n`YieldExpressions` in the block.\n\n```csharp\npublic class Example\n{\n    public void ExampleYield()\n    {\n        // Create an enumerable block that yields values\n        var index = Variable( typeof(int), \"index\" );\n\n        var enumerableBlock = BlockEnumerable(\n            [index],\n            For( Assign( index, Constant( 0 ) ), LessThan( index, Constant( 10 ) ), PostIncrementAssign( index ),\n                Yield( index )\n            )\n        );\n\n        // Compile and execute the enumerable block\n        var lambda = Lambda\u003cFunc\u003cIEnumerable\u003cint\u003e\u003e\u003e( enumerableBlock );\n        var compiledLambda = lambda.Compile();\n        var enumerable = compiledLambda();\n\n        foreach( var value in enumerable )\n        {\n            Console.WriteLine( $\"Yielded value: {value}\" );\n        }\n    }\n}\n```\n\n### Using Expression\n\nThe following example demonstrates how to create a Using expression.\n\n```csharp\npublic class Example\n{\n    private class DisposableResource : IDisposable\n    {\n        public bool IsDisposed { get; private set; }\n        public void Dispose() =\u003e IsDisposed = true;\n    }\n\n    public void ExampleUsing()\n    {\n        var resource = new TestDisposableResource();\n\n        var disposableExpression = Expression.Constant( resource, typeof( TestDisposableResource ) );\n        var bodyExpression = Expression.Empty(); // Actual body isn't important\n\n        var usingExpression = ExpressionExtensions.Using( \n            disposableExpression, \n            bodyExpression \n        );\n\n        var compiledLambda = Expression.Lambda\u003cAction\u003e( reducedExpression ).Compile();\n\n        compiledLambda();\n\n        Console.WriteLine( $\"Resource was disposed {resource.IsDisposed}.\" );\n    }\n}\n```\n\n##
