isPunctuation and isSymbol are defined in terms of GeneralCategory, which derives Read, and GHC.Read imports Text.Read.Lex.
Ah, gotcha.
We could move GeneralCategory and generalCategory to GHC.Unicode and standalone derive Read instance in GHC.Read or Data.Char; acceptable?
Probably more acceptable than the boot file; I'll defer to hvr on this subject though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10444#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
