Comment:
Indeed Duncan is right. Specifically, `-fglasgow-exts` sets the following
flags, and that is its only effect
{{{
Opt_PrintExplicitForalls
, Opt_ForeignFunctionInterface
, Opt_UnliftedFFITypes
, Opt_GADTs
, Opt_ImplicitParams
, Opt_ScopedTypeVariables
, Opt_UnboxedTuples
, Opt_TypeSynonymInstances
, Opt_StandaloneDeriving
, Opt_DeriveDataTypeable
, Opt_FlexibleContexts
, Opt_FlexibleInstances
, Opt_ConstrainedClassMethods
, Opt_MultiParamTypeClasses
, Opt_FunctionalDependencies
, Opt_MagicHash
, Opt_PolymorphicComponents
, Opt_ExistentialQuantification
, Opt_UnicodeSyntax
, Opt_PostfixOperators
, Opt_PatternGuards
, Opt_LiberalTypeSynonyms
, Opt_RankNTypes
, Opt_ImpredicativeTypes
, Opt_TypeOperators
, Opt_RecursiveDo
, Opt_ParallelListComp
, Opt_EmptyDataDecls
, Opt_KindSignatures
, Opt_PatternSignatures
, Opt_GeneralizedNewtypeDeriving
, Opt_TypeFamilies ]
}}}
So I'll close this ticket. Fergus if some of these flags are too coarse-
grained, open another ticket.
