With a speed penalty of about a factor 2,
|
|
Don Beaudry's functor module provides you with the
|
|
partial closure functionality which you would like.
|
|
Please get the current version from ftp.python.org,
|
|
it works with Python 1.5 .
|
|
|
|
BTW, I think you will go back to the default parameter
|
|
trick after a while, since it is faster, which might be
|
|
an issue for callbacks.
