I found that I (like Alex Martelli, http://mail.python.
org/pipermail/python-dev/2006-February/060341.html :-)
am writing lambdas like "lambda x: x.do_smth(a,b,c)" a
lot (often for filter/map functions). So, I think it
would be great to have such a function implemented in
C and placed in the standart library. Operator module
can be a good place for it.
