According to the comments in the patch, it would ''not'' solve the problem
addressed here:
{{{
Now sage_getsourcelines works similarly for old and new style classes:
sage: sage_getsourcelines(Sets.ParentMethods)
sage: sage_getsourcelines(Sets.Algebras)
Still both fail, because inspect.getsourcelines (in fact
inspect.findsource) fails on nested classes which have been renamed
with NestedClassMetaclass:
...
}}}
The point is that both ''do'' work with my patch:
{{{
sage: from sage.misc.sageinspect import sage_getsourcelines
sage: for x in sage_getsourcelines(Sets.Algebras)[0]:
....: print x,
....:
class Algebras(AlgebrasCategory):
def extra_super_categories(self):
"""
EXAMPLES::
sage: Sets().Algebras(QQ).extra_super_categories()
[Category of modules with basis over Rational Field]
sage: Sets().Algebras(QQ).super_categories()
[Category of modules with basis over Rational Field]
sage: Sets().example().algebra(ZZ).categories()
[Category of set algebras over Integer Ring,
Category of modules with basis over Integer Ring,
...
Category of objects]
"""
from sage.categories.modules_with_basis import
ModulesWithBasis
return [ModulesWithBasis(self.base_ring())]
}}}
