js function-shortcut macro

gistfile1.js

macro λ {	
	case $params $body => {
		(function $params $body)
	}
	case $name:ident $params $body => {
		(function $name $params $body)
	}
}

var a = λ (a) {
	console.log(a); 
};

a('hello world');

Shamelessly copied from sweetjs.org. Instead of def, use λ
