Using "gchi -fglasgow-exts", I want to turn off glasgow extensions. First I try:
Prelude> :unset -fglasgow-exts can't unset GHC command-line flags
Prelude> :set -fno-glasgow-exts Prelude> :t 5 5 :: (Num t) => t
So GHCi is capable of turning off glasgow extensions, but is apparently really picky about what command is used to do it.
sorear suggested I file this as a bug.
