Hello I have a failing test in BuildWrapper when moving from GHC 7.0.4 to 7.4.1. As far I can tell, in the TypecheckedSource I get DataCon objects that have no location info, and hence I can't retrieve them by location... Which is useful in a IDE (tell me what's under my mouse cursor, tell me where else it's used). Given the simple data declaration: data DataT=MkData {name :: String} In 7.0.4 I obtain a hierarchy that ends in FunBind (on a Var called "name")/MatchGroup/Match/ConPatOut and the contained DataCon named "MkData" has a SrcSpan associated with it, and so do the Var, MatchGroup and Match. In 7.4.1 I have the same hierarchy but the DataCon tells me "no location info". The Var "name" has a location, but the MatchGroup and Match don't either. Is it a normal change? Do I need to change something in the way I load the module? Is it a regression? Thanks! -- JP Moresmau http://jpmoresmau.blogspot.com/
