That one syntax sugar library you (may have) wished you wrote yourself.

This library provides the `for_let!` macro, so you can write code like this:

```rust

for_let!(Some(Complex(Pattern(foo))) in iteratee {

    // do stuff

});

```

Which is just sugar for this:

```rust

for el in iteratee {

    match el {

        Some(Complex(Pattern(foo))) => {

            // do stuff

        }

        _ => {}

    }

}

```

Accepts all patterns that are legal in a match arm. How Pythonic!
