Yeah, I like that.  Or, to save some typing:
  prnt = lambda x: print(list(x))

Of course, but it would mean evaluating an expression every time I
defined my function.  That just seems unhygenic

Ah!  I should've thought of that.

Well, that's why I rferenced the other article,
http://www.artima.com/forums/flat.jsp?forum=106&thread=211200#275387),
to show that other people have the same expectations.  (In the
article, Carl Johnson correctly points out that the real problem is
that str() responds to generators differently than do the other
collection types.)
