When a function returns a tuple, you can omit the parentheses from the
target variables, like:
a, b = foo()
instead of
(a, b) = foo()
But it seems you can't when setting up a for loop:
for i, x in enumerate(all_my_foos)
# do something
end
# throws an "syntax: invalid iteration specification"
But it works if I put parens around "i, x". Is this intentional? It's not a
big deal to put the parens, but it did trip me up a bit as I expected the
same behavior as normal function application, and coming from Python I'm
very used to using enumerate in this way.
