Re: [isabelle] Unexpected assumptions in nested contexts
it seems that your message was at least considered, see
Unfortunately that was not visible on the isabelle-users mailing list.
As far as I can tell (from looking at the development version of
Isabelle), the next Isabelle release will behave as expected on your
example, i.e., the result will be:
finite ?I ⟹ ?something_about ?I

Nesting two contexts, where the inner context makes assumptions about
fixed variables from the outer context, results in unexpected
all-quantified assumptions. Consider this minimal example:
fixes I :: "'a set"
assumes I: "finite I"
lemma test: "something_about I"
Looking at the fact `test` from outside both contexts with `thm test`, I
(!!I. finite I) ==> ?something_about ?I
Obviously, this fact says something completely different. Am I doing
something wrong here?
