Hi,
I only noticed now that set/dict comprehensions were backported to 2.7
without letting the loop Variables leak into the surrounding scope. So they
now behave different from list comprehensions. Is this intentional or just
a backporting oversight?
I'm asking because we had a discussion about the 'right' semantics several
times on the Cython list, and the current behaviour is that all
comprehensions leak when compiling Py2 code and the do not leak when
compiling Py3 code. I would hate to fix that up to match 2.7 and then see
that the behaviour in Py2.7 is to be considered an accident.
Stefan
