B> Since this won't work, 

 Personnally, I think this is the right way to do it. Unfortunately in this
 example a poor choice was made for the name of the alias method because
 ruby interpret 

      _===(other)

 as
      _().===(other)

 i.e. it will try to call the method `_' and if this method return a string
 it will enter in an infinite loop.

 If you replace `_===' with, for example, `eqq' it will work.
