prefer Binding.name_of over Binding.print -- the latter leads to funny quotes and markup within the constructed term;

always transfer thm where attributes are applied -- relevant for internal 'notes' (e.g. via bundle 'includes') in contrast to external 'notes' (cf. Proof_Context.retrieve_thms);

proper context;

tuned

moved derivation of ctor_dtor_unfold to sugar (streamlines fp_result interface)

export one more ML function, needed for primcorec

reverted 6c5e7143e1f6; took a better look at evaluation data this time

tuned unchecked ML;

removed junk;

ignore trailing primes, e.g. rename \<alpha>' to \<alpha>'' instead of \<alpha>'a;
