Re: [isabelle-dev] HOL-Algebra

Hi all,

just a few comments on my behalf.

Seems to make sense.

This pragmatic tradition had been started by »Orderings.thy«; I'm
uncertain whether it is worth the effort to change it.

Note that the theories »More_*.thy« contain material contributed by
Jeremy Avigad but not situated in HOL-Algebra in the first place; when
collecting this I did not want to touch the original theories, but as
part of a rework those theories could be integrated.

Cheers,
Florian

distangling the ancient misunderstaning of char in Isabelle vs. various
character-related types in several target languages may indeed come at a
certain price in exotic situations; anyway I will have a look at those
sessions whether something meaningful can be derived from them.

Cheers,
Florian
