In that case, 'alias' wouldn't alias anything; it just makes a copy,
which is a different thing altogether.

It seems more likely to be something likc Yossef said:

block = Proc.new { "Parent" }
define_method :real_method, block
define_method :fake_method, block

Where the same body (rather than two identical copies) is used for
both methods; the traditional CS kind of "alias".  In UNIX terms, it's
an ln, not a cp.

To stretch the analogy a bit, what I was expecting was more like "ln -
s".  But clearly that's not correct, so I'll just stick with the
wrapper methods.

Thanks for all the replies.
