#10907: Factorization is not coercion-friendly
------------------------+---------------------------------------------------
Reporter: lftabera | Owner: robertwb
Type: defect | Status: new
Priority: major | Milestone: sage-4.7
Component: coercion | Keywords: Factorization, coercion
Author: | Upstream: N/A

I get the following:
{{{
sage: K = QQ[x]
sage: f1 = K.random_element()
sage: f2 = K.random_element()
sage: f= f1*f2
sage: F = factor(f)
sage: f-F
...
TypeError: unsupported operand parent(s) for '-': 'Univariate Polynomial
Ring in x over Rational Field' and '<class
'sage.structure.factorization.Factorization'>'
sage: F-f
0
sage: f == F
False
sage: F in K
False
}}}
I think that at least f-F should work.
