      Linear types (#15981) · 40fa237e
      Krzysztof Gogolewski authored and Ben Gamari's avatar Ben Gamari committed
      This is the first step towards implementation of the linear types proposal
      (https://github.com/ghc-proposals/ghc-proposals/pull/111).
      
      It features
      
      * A language extension -XLinearTypes
      * Syntax for linear functions in the surface language
      * Linearity checking in Core Lint, enabled with -dlinear-core-lint
      * Core-to-core passes are mostly compatible with linearity
      * Fields in a data type can be linear or unrestricted; linear fields
        have multiplicity-polymorphic constructors.
        If -XLinearTypes is disabled, the GADT syntax defaults to linear fields
      
      The following items are not yet supported:
      
      * a # m -> b syntax (only prefix FUN is supported for now)
      * Full multiplicity inference (multiplicities are really only checked)
      * Decent linearity error messages
      * Linear let, where, and case expressions in the surface language
        (each of these currently introduce the unrestricted variant)
      * Multiplicity-parametric fields
      * Syntax for annotating lambda-bound or let-bound with a multiplicity
      * Syntax for non-linear/multiple-field-multiplicity records
      * Linear projections for records with a single linear field
      * Linear pattern synonyms
      * Multiplicity coercions (test LinearPolyType)

      The latter is apparently not supported by busybox.

      Move CLabel assertions into smart constructors (#17957) · eb8115a8
      Sylvain Henry authored and Marge Bot's avatar Marge Bot committed
      It avoids using DynFlags in the Outputable instance of Clabel to check
      assertions at pretty-printing time.

      Just adding `{-# LANGUAGE BangPatterns #-}` makes the two other metrics
      fluctuate by 13%.
