Philip Jenvey <pjenvey at underboss.org> added the comment:

The length-hint branch was merged to default and is included in the pypy 2.0 
betas. It adds PEP 424 support and also optimizes list creation/extend for 
generic iterables such as xrange.

Last time I checked this list(xrange(10000000)) case is now significantly faster 
than CPython

release:  -> 2.0
status: chatting -> resolved
