sysf: impl renaming of forall binders but then backed out
...
- capture when applying forall is ok since binder is renamed as well
- and since type names are valid binder names, this is ok
- TODO: what if we call inst with non-base type?
- add more variable capture tests
- typecheck: type= handles alpha-equiv
