I use lambda quite a bit in both Python and Scheme: in the same
places in both:
1) to create a function to be passed to map/filter/reduce
2) to create functions to hook to GUI widgets (esp. e.g. in a
loop).
Thinking up good names for things is the hardest part of
writing a program. Why bother naming something you don't have
to?
