#instance_methods on a singleton class

[Xavier Noria]

Given:

class C
def self.m; end
end
class D < C; end

the superclass of the singleton class of D is the singleton class of C. However

(class << D; self; end).instance_methods(false)

includes m, both in 1.8 and 1.9. Is that intentional or is it a bug?

Given:

=C2=A0 =C2=A0class C
=C2=A0 =C2=A0 =C2=A0def self.m; end
=C2=A0 =C2=A0end
=C2=A0 =C2=A0class D < C; end

the superclass of the singleton class of D is the singleton class of C.

Just a remark here. That's what Flanagan & Matz says, but the draft of
the spec says that the superclass of an eigenclass is implementation
defined, and that the singleton class of D has the singleton class of
C among its superclasses.

So the question still holds, either the spec is wrong, or there's a
bug I believe. Perhaps I should ask in -core.
