This slipperly path looks like one followed by a certain other language.
The fact that ruby has variadic functions and optional parens causes some
unpleasant ambiguities, but I'd rather ruby raise a SyntaxError when it
doesn't know what you mean, rather than "cleverly" trying to figure it out.
Now *I* have to figure out what ruby is going to figure out based on what it
thinks I'm thinking... I just wanna write code, not play mind games with a
compiler!

For me at least, ruby's syntax is hovering near the edge of "too complicated".
Please don't push it over :)
