[Python-Dev] PEP 309, function currying

I've updated PEP309 a little, since someone sent me a better implementation.
I haven't mentioned in the latest version the recent objection by Dave Abrahams that:
Several languages have misused the term "curry" this way
mostly on the grounds that the main language using curry that way is English :)
The first Google result I found that mentioned function currying was this:
[ http://www.engr.uconn.edu/~jeffm/Papers/curry.html ] Function Currying in Scheme
I'll quote from the abstract:
Function currying is the process of partially, or incrementally, supplying arguments
to a function. Curried functions are delayed functions expecting the remainder of the
arguments to be supplied. Once all the arguments are supplied, the function evaluates normally.
I haven't the time for an exhausive statistical and linguistic analysis. My vote goes for the
prevalent definition of currying that is actually a useful functional programming abstraction,
i.e. the one described above.
Anyway, this is my last request for flames about the presentation and content of the PEP itself
before I post a full draft of the proposed 'functional' module.
