    -- * Domain and Purpose
    --
    --     GHC.JS.Ident defines identifiers for the JS backend. We keep this module
    --     separate to prevent coupling between GHC and the backend and between
    --     unrelated modules is the JS backend.
    --
    -- * Consumers
    --
    --     The entire JavaScript Backend consumes this module including modules in
    --     GHC.JS.\* and modules in GHC.StgToJS.\*
    --
    -- * Additional Notes
    --
    --     This module should be kept as small as possible. Anything added to it
    --     will be coupled to the JS backend EDSL and the JS Backend including the
    --     linker and rts. You have been warned.
