There is an interesting discussion on continuations on the Scheme
Request for Implementation mailing list (SRFIs as something like
PEPs).  The thread index is here:

The thread seems particularly relevant given the current questions
about how and whether the stackless changes should be incorporated
into Python 2.1.

Matthias Felleisen asked the reverse question about Scheme.
