An [eslisp][4] macro that works like an the usual `lambda` expression macro but

also

-   parses *splats* (atoms starting with `...`) in the arguments and turns them

    into appropriate variable assignments prepended to the function body, and

-   implicitly returns the last thing in the body if it's an expression.

Note that despite the name, this module is strictly a *function expressions*

(`lambda`-ish) macro, not a function declaration.  I'll rearrange that

eventually.

## Example

    (macro fun (require "eslisp-fancy-function"))

    (fun (a b ...c d) (* a b d))

↓

    (function (a, b) {

        var c = Array.prototype.slice.call(arguments, 2, -1);

        var d = arguments[arguments.length - 1];

        return a * (b * d);

    });

See [the tests][5] for fuller usage.
