Of course, thanks.  I've played around some more and found my cases
must be slightly ambiguous.  Like this:

def func arg
  [0, 1, 2]
end

a, b, c = func "arg"   --> error
a, b, c = func("arg")  --> ok
a, b, c = (func "arg") --> ok

Why doesn't the first form work?  Is it assigning 'func' to 'a' (or
'c'?)  and then coming across '"arg"' and going WTF?
