Comment (by SimonKing):
Adding
{{{
def _coerce_map_from_(self,S):
if not hasattr(self,'_s'):
return None
try:
S_to_s = self._s.coerce_map_from(S)
except:
return None
if S_to_s is None:
return None
return self.coerce_map_from(self._s)*S_to_s
}}}
to `MacdonaldPolynomials_generic` solves the problem. But I first have to
check whether the original coercion from P to Ht (which exists if one does
''not'' do `m(P.one())`) is the same.
