<br>
Vlad has found what looks like a clear gap in the interaction between<br>
two extensions: -XStandaloneKindSignatures and -XExtendedForAllScope.<br>
<br>
I think it's quite obvious that under -XExtendedForAllScope the forall<br>
in a standalone kind signature should behave like the forall in a<br>
standalone type signature, i.e. it should scope over the definition<br>
as well.<br>
<br>
I recommend accepting this amendment to StandaloneKindSignatures.<br>
