I see your point, but:

require 'enumerator'

h = House.new
h.enum_for(:each_bathroom).select {|b| ... }

I *really* don't see how yours is much better. In fact, I'd argue the
enumerator one is better because it is more explicit...anyone who
knows how enumerator works can see what is happening. Only you, me and
the people paying attention to this thread would understand what the
EnumeratorArgs thing was doing.

But I guess we will just have to agree to disagree, since we are both
dragging this into one of those endless discussions threads that I
dislike so much ;)
