Vladislav Zavialov in https://github.com/ghc-proposals/ghc-proposals/pull/605 https://github.com/ghc-proposals/ghc-proposals/pull/605 proposes a small fix to #281, namely that for

f :: forall x -> Show x => x -> String f (type t) = show @t

to work, ExplicitNamespaces and RequiredTypeArguments is sufficient, and we should not also require ScopedTypeVariables, which we are moving away from.

I’ll shepherd this myself, and I suggest acceptance.

Cheers, Joachim
