    Narrow scope of special-case for unqualified printing of names in core libraries · e2c91738
    Ben Gamari authored
    Commit 547c5971 modifies the
    pretty-printer to render names from a set of core packages (`base`,
    `ghc-prim`, `template-haskell`) as unqualified. The idea here was that
    many of these names typically are not in scope but are well-known by the
    user and therefore qualification merely introduces noise.
    This, however, is a very large hammer and potentially breaks any
    consumer who relies on parsing GHC output (hence #11208). This commit
    partially reverts this change, now only printing `Constraint` (which
    appears quite often in errors) as unqualified.
    Fixes #11208.
    Updates tests in `array` submodule.
    Test Plan: validate
