#11393: Ability to define INLINE pragma for all instances of a given typeclass -------------------------------------+------------------------------------- Reporter: danilo2 | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 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 simonpj): I'm not sure this is a good plan. * What if someone writes a bug instance declaration? Having an `{-# INLINE #=}` pragma written somewhere else entirely might be highly unexpected. * The `{-# INLINE #-}` pragma in a class decl applies to the default method declaration in that class decl. We'd need a way to get the current behaviour (i.e. inline the default method, but no effect on instances that define their own method for `foo`). Seems doubtful to me.
