-Parser should check that:
+- for multiple simultanously defined functions, compatibility cases should fold the

+Nominal_Datatype Parser should check that:
 
 - types of bindings match types of binding functions
 - fsets are not bound in lst bindings

 Smaller things:

+- maybe <t1_t2>.perm_simps should be called permute_<type>.simps;
