For what it's worth, I'm a *huge* fan of Ruby's {|-style blocks.
Also, it's worth noting that "do...done" seems to be a bit more
popular in Ruby programs that I've seen.
I'm not a fan of the fact that these blocks have different behavior
than "regular" functions and methods, but that's a qualm for a
different mailing list, and I'm not a rubyist anyhow :)
Consider this: w = (x)->y || z
That code is not obvious at all. Which of these would it be?
1: w = function (x) { return y } || z
2: w = function (x) { return y || z }
It seems to me that there must be some sort of delineation around the
function start and end. I agree that "function ... return" is way too
many characters to write and read for such a fundamental bit of
syntax.
This style is quite clear and readable:
w = {|x| y || z}
w = {|x| y} || z
However, that's pretty awful to type. Perhaps even worse than ->.
Maybe {(x) y || z} might be better? Of course, that would break
blocks that start with parenthesized sequence blocks, but is that
really a concern? Blocks in JS are useless, can't we just do away
with them?
