Comment (by darij):
In other news, I'm still trying to understand why `Sets().Algebras(QQ)`
needs to make sense. This here is seriously weird:
{{{
sage: Sets().example()
Set of prime numbers (basic implementation)
sage: Sets().example().algebra(QQ)
Free module generated by Set of prime numbers (basic implementation) over
Rational Field
sage: Sets().example().algebra(QQ) in Algebras(QQ)
False
sage: Sets().example().algebra(QQ) in Sets().Algebras(QQ)
True
}}}
