Hallo,

I noticed that setsum.cong, setprod.cong etc. are not declared as
fundef_cong. This is important for function-package function definitions
where a recursive call occurs under a setsum or setprod. Without these
declarations.

Is there a reason not to put these declarations into Groups_Big? If not,
is it unproblematic to simply add the declaration to the cong lemma in
the locale comm_monoid_set, or should only setsum.cong and setprod.cong
be declared as fundef_cong rules explicitly?

Cheers,

Manuel
