There should be no visible efficiency difference. I still always use the
reserved keyword "alias", but I'd also agree if it was planned to remove
it in a future version. The reason is consistency. Some of us also think
that this: 

class A < B
	blah
end

should change to:

A = Class.new(B) {
	blah
}

and similar things.
