Comment #106 on issue 1598 by smichr: New polynomials manipulation module
http://code.google.com/p/sympy/issues/detail?id=1598
Returning expression that are unevaluated (evaulate=False) I suspect is
what is
causing some strange behaviors in my branch where o.is_commutative is
coming back
with an error saying that o doesn't have the commutative property...I'm
trying to get
a good test case to show, though. In the meantime, consider:
a=Mul(*[2,1+x], evaluate=False)
b=2*(1+x)
a==b
False
a=Mul(*[x,k])
b=x*k
a==b
True
a=Mul(*[x,k],evaluate=False)
a==b
False
factor (is it?) sends back things unevaluated so as not "to lose
information" of the
factoring...this may cause problems. Anyone else noticing anything strange?
