I'm only going to be here through late March... given the change to
the 4th Thursday, I'd need to do this next month (February) or not at

Here's an abstract:
Factory is an object-oriented approach to partial function
application, also known as currying.
Python 2.5 added support for currying with the addition of
The Factory module is a more powerful implementation of this pattern.
Some improvements include:
- safer, as invalid arguments are detected immediately, instead of
at call time
- intelligent support for classes, instance methods & all other
- bound arguments can be inspected and modified as attributes
- several convenient methods for (re)binding arguments
Using Factories can:
- simplify writing callbacks
- reduce bugs in concurrent applications
- provide easy lazy evaluation
This talk will demonstrate the Factory module and discuss its
implementation and uses. Familiarity with currying is helpful but not
required. More information is available at http://pypi.python.org/pypi/Factory/
The talk itself consists mainly of a live demo of the module, followed
by a brief review of its implementation. It falls more on the side of
"cool things you can do that are unique to Python", in contrast to the
more typical "how to parse TPS reports in Python (or Perl or Java
or ...)" . As such, it's a good insight in to the power of Python for
programmers new to the language, while providing plenty to keep old
hands entertained. I presented this talk to the Chicago group in
September and it was very well received, with one audience member even
suggesting the module should be included in the standard library.

Sure. $DIETY knows, I like to talk. ;-)
