Dear Sage team,
i am puzzled by the fact that introspection does not work for the hash
method, while it works for other special methods.
I applied Martin's patch for ticket #3724, which provides a new hash
method for matrices over GF(2) and also contains examples in the doc
string. But the doc string seems invisible for introspection:
sage: M = MatrixSpace(GF(2),10000,10000).random_element()
sage: M.__hash__?
Type: method-wrapper
Base Class: <type 'method-wrapper'>
String Form: <method-wrapper '__hash__' of
sage.matrix.matrix_mod2_dense.Matrix_mod2_dense object at 0x31909e0>
Namespace: Interactive
The same happens with
sage: L=(1,2)
sage: L.__hash__??
The same also happens if i apply it to the hash methods of the
extension classes that i created.
Is it a bug of introspection?
Martin suggested i shall open a ticket for it, but i wanted to ask
here - perhaps i did something stupid, and the doc string is supposed
to be gotten in a different way?
Yours
Simon
