I just hit this bug in the wild while doing some modular forms computations:
masiao@fermat:~$ sage ---------------------------------------------------------------------- | Sage Version 5.3, Release Date: 2012-09-08 | | Type "notebook()" for the browser-based notebook interface. | | Type "help()" for help. | ---------------------------------------------------------------------- sage: M = ModularForms(Gamma0(17), 4) sage: v = M.q_expansion_basis(prec=10)[0] sage: v in M False Oddly "M(v)" works if v corresponds to a q-expansion of a form in M, and raises an error if it doesn't -- as it should do -- so there is something going wrong in the code for __contains__. Does anyone know what might be causing this? David -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
