Re: [isabelle] print_statement and sorts

Using show_sorts is also not what I really want, as the sort-annotations

theorem order_refl:

The best way might be to make print_statement only print non-default
sorts in the fixes-part.

There is a deeper problem here: the simulteneous "uncheck" phase for types/terms before printing should take care of constraints, and reduce them to a sensible minimum. It doesn't do that for various historic reasons: the scope is just a single type or term.

It has required some years to make the dual "check" phase use constraints simulteneously, and "uncheck" might require some time to get there as well.
