Paul,

Without comment on the merits of the PEP, it seems out of date to me. 
The PEP presents three different implementations of curry (one in
Pyrex) without clarifying which one is the preferred one.  It presents
a summary at the end that would make more sense at the beginning.

I would revise the PEP to:

1. Clearly describe what is being implemented for 2.4.  Provide a
specification for the behavior along with examples of use.  Make sure
you cover all the corner cases, e.g. can you provide a keyword arg
without providing positional args.

2. Provide a rationale for why this belongs in the standard library.

3. Describe the @ syntax, but put it in a self-contained section and
explain why it was not implemented.
