Subject: [BUG?] Fun with aliases

Moin!

Just thought I'd mention this:

C:\>ruby
alias $! $foo; $foo = 5; begin; raise "foo"; rescue => err; p err; end
^D
5

However:

C:\>ruby
alias $! $foo; $foo = 5; begin; raise "foo"; rescue Fixnum => err; p 
err; end
^D
-:1: foo (RuntimeError)

I'm using  ruby 1.8.1 (2003-12-25) [i386-mswin32]  and I'm able to 
reproduce the same behavior with  ruby 1.8.0 (2003-08-04) [i686-linux-gnu].

Which means Ruby still knowns which exception was really raised, but 
misrepresents it in case you're rescuing it to a variable.

I couldn't produce any crashes or other weird things by aliasing any 
other global variables, by the way.
