It's not that "it's too much to grok", it's that as I like that (blocks) syntax
so much, I'd prefer to use it for (shorter) functions (syntax) instead of the
(ugly, extraneous, imho) "arrow syntax proposal", not for blocks.
Also, I wonder if in order to make blocks first class, do we need any new
syntax ?
function f() {
a.forEach({ return 3 });
}
?
