In Re: Module Naming Dilemma, Anonymous Monk asked why I wasn't simply aliasing typeglobs together for some code I was working on. Ignoring the fact that I wanted to minimize that behavior, I was kind of stumped by the following code snippet:

  #!/usr/local/bin/perl -lw
  use strict;

  package Foo;
  sub new  { print "Expected class: $_[0]"; bless {} => shift }
  sub test { print "Actual class: ". ref shift }

  package main;
  *Bar:: = \*Foo::;
  Bar->new->test;
  Foo::new('Bar')->test;
[download]

Both times that test() is called, I would expect ref to return Bar but it instead returns Foo. Why is that?

I (once again) cannot find where this behavior is documented, even though I suspect it is. Frankly, this code does not do what I would expect it to to do.
