#10858: Smaller generated Ord instances -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #9557 | Differential Revisions: -------------------------------------+------------------------------------- Comment (by simonpj): I'm not following the details here but: * I think it's an excellent idea to use `thenCmp` (will dramatically simplify the output of `-ddump-deriv`) * But I suspect it won't make a lot of difference in the end, because GHC will probably inline `thenCmp`! But what is stranger to me is this: why don't we just derive the code for `compare`, and use the default methods for `(>)`, `(==)` etc?
