-----------------------------+--------------------------------------
The method `NumberField_generic.pari_bnf()` does not detect if the PARI
`bnf` has already been certified and therefore always calls
`bnfcertify()`. This is due to name-mangling of double-underscore
attributes; more precisely,
{{{
getattr(self, "__pari_bnf_certified", False)
}}}
should be
{{{
getattr(self, "_NumberField_generic__pari_bnf_certified", False)
}}}
