Actually, Simon understood me perfectly. I don't see any value in the dotted version. There's two uses of dots in filenames: 1) As just another character - like including a ', @, $ or whatever in a filename. I'd disallow all of these since they're not legal Haskell module names so they don't fit into the hierarchical naming scheme. 2) Part of either . (current directory) or .. (parent directory). I'd disallow these because they aren't needed now we have hierarchical libraries. Note that the ghc-users discussion would have a quite different semantics from what Hugs has. Hugs semantics is to simultaneously try to interpret filenames two ways: first relative to the current directory, and second relative to the search path. The proposed semantics is to either treat it as relative to the current directory if it contains a leading dot or to treat it as relative to the search path otherwise. -- Alastair ps Thing to watch for in applying proposed change: runhugs should continue to accept arbitrary filenames but they should always be interpreted as filenames relative to the current working directory. This is necessary so that the usual #! magic will work. _______________________________________________ Hugs-Users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/hugs-users
