Topic: [isabelle] Multiset orderings -- < vs. <#

From: Florian Haftmann <florian.haftmann@informatik.tu-muenchen.de>
In a recent off-line discussion is was suggested that the notation of
the two orderings in HOL/Library/Multiset.thy should be swapped, i.e.

< -- the pointwise ordering
<# -- the multiset order

This would establish a closer correspondence to ordinary sets and allow
us to use more type classes from the orderings / lattices hierarchy.

Any comments or objections?
