 {{{#!diff
              sage: Sym =
 SymmetricFunctions(FractionField(QQ['t'])).macdonald()
              Traceback (most recent call last):
              ...
 -            ValueError: parameter q must be in the base ring

 }}}
 Is this a regression in terms of the error message, an improvement, or
 just a change?  To me it seems more confusing but maybe that's an
 appropriate message for users of this material.
