#7918: SrcSpan's associated with expanded quasi-quotes are inconsistent -----------------------------------------+--------------------------------- Reporter: edsko | Owner: edsko Type: bug | Status: new Priority: high | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Test Case: quasiquotation/T7918 | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: -----------------------------------------+--------------------------------- Comment (by edsko): So actually I agreed with you that the special case was undesirable, which is why I had (for types, not yet for expressions) got rid of rnHsType completely, and defined only rnLHsType. This way the exceptions you mention are taken care off statically, which is much better. Your suggestion is an alternative; I thought about it but I thought I'd need to add a new constructor to HsExpr/HsType/Pat/..; didn't realize that I could use the constructor for parens. Do you prefer I use HsPar and co instead of removing rnHsExpr (rnHsType, ..)? It certainly would be a less intrusive change I guess. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7918#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
