    Guard CUSKs behind a language pragma · a5fdd185
    Vladislav Zavialov authored
    GHC Proposal #36 describes a transition plan away from CUSKs and to
    top-level kind signatures:
    1. Introduce a new extension, -XCUSKs, on by default, that detects CUSKs
       as they currently exist.
    2. We turn off the -XCUSKs extension in a few releases and remove it
       sometime thereafter.
    This patch implements phase 1 of this plan, introducing a new language
    extension to control whether CUSKs are enabled. When top-level kind
    signatures are implemented, we can transition to phase 2.
