golang package for enhanced errors that capture file and line number information, the call stack, relevant identifiers, and a handle back to the original error for type switching.

Replacement for fmt.Errorf(...):

```go

err := errors.Errorf("Failed to do something; here's a value %v",len(data))

fmt.Printf("%#v\n",err) // Prints full stack trace.

```

Wrap another function's error:

```go

_, err := net.Dial( "tcp", "localhost:8080" )

if err != nil {

    return errors.Go( err )

}

```

Obtain the original error in order to type switch:

```go

func connect() error {

    _, err := net.Dial( "tcp", "localhost:0" )

    if err != nil {

        return errors.Go( err )

    }

    return nil

}

err := connect()

switch errors.Original( err ).(type) {

    case *net.OpError:

        // We know the original type!

}

```
