Hi all,

RPython now has support for generators.  The support is minimal for now:

* only pre-Python-2.5 generators: no .send(), no "yield" inside a "try:finally:" block, etc.

* you cannot use a "for" loop to iterate over a generator-iterator. You have to use explicitly .next() and catch the StopIteration, for now.

* two different generators produce generator-iterator objects that the annotator cannot unify, even if they happen to yield objects of the same type.  You have to work around that limitation e.g. as shown in rpython/test/test_generator, test_cannot_merge.

I still hope that this is enough to be useful to the Prolog and Converge interpreters :-)

A bientôt,

Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
