      Implement NoFieldSelectors extension (ghc-proposals 160) · 2521b041
      Adam Gundry authored
      Fixes #5972. This adds an extension NoFieldSelectors to disable the generation
      of selector functions corresponding to record fields.  When this extension is
      enabled, record field selectors are not accessible as functions, but users are
      still able to use them for record construction, pattern matching and updates.
      See Note [NoFieldSelectors] in GHC.Rename.Env for details.
      
      Defining the same field multiple times requires the DuplicateRecordFields
      extension to be enabled, even when NoFieldSelectors is in use.
      
      Along the way, this fixes the use of non-imported DuplicateRecordFields in GHCi
      with -fimplicit-import-qualified (fixes #18729).
      
      Moreover, it extends DisambiguateRecordFields to ignore non-fields when looking
      up fields in record updates (fixes #18999
      
      ), as described by
      Note [DisambiguateRecordFields for updates].
