FWIW we've been talking a long time ago about a simple lowering - if the
last argument to a function is a delegate, allow moving the delegate's
body outside of the function:
fun(a, b, c) { body }
|
V
fun((a, b, c) { body });
As far as Walter and I could tell, there are no syntactical issues
created by such a lowering. But we've been wrong about that in the past
(me 10x more often than him).

This would be awesome. I think Ruby and Scala have one of the best
syntax for code blocks/delegates. Until then we can use this somewhat
ugly hack:
fun(a, b, c) in {
// body
};
For the above to work "fun" should return a struct which implements the
opIn method.
