Note: I perfectly understand the goal of Minimal Python: do *not* change
the language or parts of it (yet), just experiment with a minimal intepreter.
That said, since Holger asked for desciptions of links here it goes:
Both www.mozart-oz.org and pliant.cx (and others) are interesting for
they rely on a minimal intepreter that lets one define part of the
language itself (and basic ones like loop structure, for example).
It can also be remarked that a good part of theoritically elegant languages
(who said lisp?) rely on minimal interpreters. Having Python move
forward in that direction may guarantee a nicer future for the language
and should be easier to do thanks to the support of its large community.
