Here's an oddity I recently came across in a unit test. Identical 
regexps declared with /.../ will be equivilent to each other, but not to 
the same regexps created with %r{...}:

   $ ruby -ve 'p( /\/blah/ == /\/blah/ )'
   ruby 1.8.2 (2004-07-29) [i686-linux]
   true

   $ ruby -ve 'p( %r{/blah} == %r{/blah} )'
   ruby 1.8.2 (2004-07-29) [i686-linux]
   true

   $ ruby -ve 'p( /\/blah/ == %r{/blah} )'
   ruby 1.8.2 (2004-07-29) [i686-linux]
   false

This appears to only be the case when there is a forward slash in the 
regexp. In other words:

   $ ruby -ve 'p( /blah/ == %r{blah} )'
   ruby 1.8.2 (2004-07-29) [i686-linux]
   true

Can anyone else confirm this? Can anyone *explain* it? Or is this a bug?
