I like that. I keep having to check in irb or ri whether String#delete 
is destructive, even after 6+ years. Or what about

class String
   alias - delete
end

"foobar" - "oa"  # => "fbr"

Using an operator makes it abundantly clear that neither string is being 
modified. But then of course you don't get arity >= 2 version of delete.

Was String#- being reserved for something else?
