Here, 1 and 2 are "arguments" to the return statement. It can handle
many of them perfectly well.

This is invalid syntax - Ruby has no comma operator (unlike, say, C),
and it simply doesn't know what to do with this code. Commas are only
allowed (I hope I won't miss anything) in multiple assignment, in
method/block argument list, and in "argument lists" of some language
constructs, like return, rescue or throw.
