#14691: Replace EvTerm with CoreExpr -------------------------------------+------------------------------------- Reporter: nomeata | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.3 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): When moving this desugaring code into smart constructors that are run by the type checker, it need to be able ot use functions like `mkStringExprFS` which require `MonadThings`. But the type checker monad does not have a suitable instance: {{{ No instance for (HscTypes.MonadThings TcS) }}} Is that by design, or has just nobody bothered so far to create such an instance? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14691#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
