Comment #1 on issue 2307 by smi...@gmail.com: Duplicate methods:
as_coeff_mul and as_coeff_Mul
http://code.google.com/p/sympy/issues/detail?id=2307
They both do necessary things. If you merge the mul version into Mul then
to get the args back you have to do
c, m = e.as_coeff_Mul()
mterms = Mul.as_terms(m)
and if Mul is merged into mul then to get a Mul from the args you have to do
c, mterms = e.as_coeff_mul()
m = object.__new__(Mul)._new_rawargs(*mterms)
I like the former better. A review of usage should be made to determine
whether the two should be merged or if the new as_coeff_Mul should be
renamed.
