Just to add weight to my previous mail, you may find it interesting to
notice that my proposed syntax match nearly exactly the proposed syntax of
the new Mozilla-editored Rust programming language:
http://doc.rust-lang.org/doc/tutorial.html#closure-compatibility
call_twice({|| "I am a stack closure; });
call_twice(fn@() { "I am a boxed closure"; });
It confirms my feeling about {|| ...}: it should only be allowed in a
context where the function still exists; it's a way to return the control
back to the calling function when you need to call a "callback-able"
function for some reason. At every other place, you should use 'normal'
closures (the language-agnostic equivalent of ECMAScript functions), for
which we should have a simplified syntax (aka syntaxic sugar). I don't
bother if it has to start by @, #, %, µ, § or anyting else, but I feel
strongly about the fact we need it.
Now, I think everyone got my point, I leave the final discussion to group
members. But, at least, my message was sent. ;-)
Best regards,
François
