Just pass them all on, from #collect to #each. We assume that the 
arguments tell #each something about how to filter or otherwise process 
the elements before yielding them.

Yes. I guess it would be more rubylike to always use select for this 
sort of thing. But in the case that someone writes a library where #each 
takes arguments, this proposal would propagate that functionality to the 
other Enumerable methods.
