yield, assert, if/else, return, etc.  If we're after that kind of
consistency, why not get rid of all those statements too?  They have
already partly done it with yield, and they ended up introducing a new
separate if/else expression syntax as an alternative to the statement.

This just seems like a gratuitous change with very little benefit.  
Changing a bunch of list functions to instead return iterators is
a much deeper change that will cause larger amounts of breakage, but
it has quite a lot of benefits, so there's a stronger case for it.
