Hi Jeff,

Jumping in way late in this thread, I'll toss in my pennies and say I
still use lambda fairly regularly in one place, and it just happens to
be the very place where I learned of lambda in the first place: event
handlers for GUI programming.  I first learned the technique in Tkinter
circa 1.5.2 and still use it in wxPython.  It isn't strictly necessary,
but given the already cluttered nature of GUI programming, I'm pretty
reluctant to toss in four or five more names every time I want a
complicated event handler to get called with slightly different
arguments. Basically I use it as a poor-man's curry (if I understand
currying correctly, I've only seen conversations about it on this list
and that's the impression I was left with: that it's a way of providing
variations in the default arguments to a function).

As I know you're a wxPython user as well, I'd be curious to know how you
approach this particular problem.

Regards,
Cliff
