New description: Language pragmas like {{{ {-# LANGUAGE TypeOperators, FlexibleContexts #-} }}} or {{{ {-# LANGUAGE TypeOperators, FlexibleContexts #-} }}} parse just fine but {{{ {-# LANGUAGE TypeOperators, FlexibleContexts #-} }}} doesn't (note the missing spaces before the closing `#-}`), saying: {{{ Cannot parse LANGUAGE pragma Expecting comma-separated list of language options, each starting with a capital letter }}} An OPTIONS_GHC pragma, on the other hand, accepts either format without complaint. -- -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5401#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
