My previous message about this had a typographical error.
Two variable names, "f" and "symb", appeared in the
Module numrules, but only one name should have been used.
The Module should have read:
numrules[f_Symbol] :=
Module[{inf},
inf = StringToStream[ToString[Definition[f]]];
Length[Select[ReadList[inf, Record], StringMatchQ[#1, StringJoin[ToString[f], "[*"]]&]]
]
