Hrm, you'd probably have to scour the archives. It's one of those
things that comes up periodically and spawns a discussion thread, but
never really gets to a concrete proposal. The best I can find is this,
which never even got submitted to the official PEP repository, but
it's someone's attempt to make something that could potentially become
one, so it's a start.

The trouble is, it's really REALLY hard to pin down useful semantics
for deferred evaluation. We already have lambda functions, which cover
a lot of situations, leaving a lot of uncertainty as to what's being
handled by this new proposal - and since no proposal ever truly comes
from a single person, that results in a certain amount of chaos.
