#14541: Family over enumerated set has wrong category
--------------------------+-------------------------------------------------
Reporter: cnassau | Owner: nthiery

This happens with Sage 5.10beta1:
{{{
sage: P=Permutations()
sage: print P.category()
Category of sets
sage: print P.cardinality()
+Infinity
sage: F=Family(Permutations(), lambda i:i)
sage: print F.category()
Category of finite enumerated sets
}}}
But clearly {{{F}}} is not finite...
