[isabelle-dev] (Re-)introducing set as a type constructor rather than as mere abbreviation

I took a look at some of these. HOL-Library fails in your own Cset.thy, where presumably you know what you are doing (particularly as this theory involves execution I should stay away from it). Similarly I'm not sure I'm the right person to fix HOL-Nominal or HOL-MicroJava. PG is very fragile just now, which makes working very tiresome.

If my memory is correct, this one worked in a reasonable amount of time on hardware of the late 1990s. But it isn't that surprising that later changes could interfere with its functioning when we restore the set type. I see that it does work with auto, but it's slow, thirty seconds or more.
