Now rename_params_rule merely issues warnings--and does nothing--if the
renaming cannot be performed. Previously it raised a fatal error.
paulson [Wed, 23 Jul 1997 11:52:22 +0200] rev 3564
Now Datatype.occs_in_prems prints the necessary warning ITSELF.
It is also easier to invoke and even works if the induction variable
is a parameter (rather than a free variable).
paulson [Wed, 23 Jul 1997 11:50:26 +0200] rev 3563
Uses new version of Datatype.occs_in_prems
