I sense growing exasperation, and I do *not* have strong feelings on 
this matter, so I promise this will be my last message on this topic.

I don't really prefer 'contains(belly, beer)' over 'beer in belly'. 
Rather, it's a completeness/consistency argument: a language that 
includes these methods for string objects:

   belly.startswith(arg)
   belly.endswith(arg)

... should also include:

   belly.contains(arg)

The lack of this method increases the likelihood that a user will 
mistakenly use the find() method as a predicate.
