Hi all,

just a few comments on my behalf.

Seems to make sense.

> Just one oddity in HOL-Algebra: It claims canonical theory names like> "Group", "Ring", "Module". Thus the main HOL session needs to evade
via> non-standard names "Groups", "Rings", "Modules" (the latter is new
in> 2af1f142f855).

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
