Ondrej and I stumbled upon an issue with could_extract_minus_sign
var('t, n')
z = (-t-t*n)/n
z.could_extract_minus_sign()
this last line returns False on my machine and True on Ondrej's. We are
both running Ubuntu 9.04 and Python 2.6.2.
I think the issue is that the method makes it all the way down to the last
resort hash and I think Ondrej is using unicode and I am not (or something
like that).
I think could_extract_minus sign should have an is_Mul case that returns the
could_extract_minus_sign result on the numerator.
Any thoughts on that?
