This is closer to what I'm asking for but these are still not
instances of real code. To build a convincing argument for a new
language feature, you need to show not only a theoretical use case,
but a practical one. In general, that means you need to show that it
is a frequent need in a large code base. Finding a bunch of examples
of it in the standard library or big applications like Zope or Twisted
would be a good start. This is something that's expected of any
 I know you didn't copy these from real code anywhere because they
all have typos -- they're missing urlparse/urlretrieve as the first
arguments to partial() or prepartial().
I'm not *in*-sane. Indeed, I am so far *out* of sane that you appear a
tiny blip on the distant coast of sanity.
