Summary: __imul__ broken for new-style classes
Initial Comment:
Taken from python-list:
From: Alexander Schmolck <a.schmolck@gmx.net>:
-----
OK, after unsuccessfully trying for about half an hour to
submit this to the
sf bug tracker, I gave up:
class Breaky(object):
def __imul__(self, other):
print "imuling"
return self
sq = Breaky()
sq *=1.
gives:
Traceback (most recent call last):[...] line 10, in ?
sq *=1.
TypeError: can't multiply sequence to non-int
Unless I'm overlooking something, this is a fairly serious
bug and I can't see
a way to work around it (getattribute would presumably
work, but slow
everything down unacceptably, so the only 'solution'
seems to be to have no
inplace-multiplication).
I had the same behavior on two different machines
(running Mandrake 8.2 and
Suse 7.3).
