Currently, two Factorization object are considered to be equal if they
have the same value, but a Factorization object is not equal to its value:
{{{
sage: P.<x> = QQ[]
sage: a = x+1; b = x+2; c = x+3
sage: F = Factorization([(a,1),(b,1),(c,1)]); F
(x + 1) * (x + 2) * (x + 3)
sage: F1 = Factorization([(a*b,1),(c,1)]); F1
(x + 3) * (x^2 + 3*x + 2)
sage: F2 = Factorization([(a,1),(b*c,1)]); F2
(x + 1) * (x^2 + 5*x + 6)
sage: F == F1
True
sage: F == F2
True
sage: F1 == F2
True
sage: F == a*b*c
False
}}}
Is this normal? (It seems to me really weird.)
PS: Am I supposed to ask this kind of questions here or is there a better
place?
