[pypy-issue] [issue967] itertools.imap significantly (order of magnitude) slower than map or gencomps

[Xavier Morel]

Xavier Morel <bugs.pypy.org at masklinn.net> added the comment:

Oh. That's weirteresting. Why does that happen even though list + gencomp has no
issue, is is something which does not behave correctly in list+imap or is it
that there's an optimization applied to list + gencomp making it close to a
listcomp?
