Currently
-fglasgow-exts
implies
-fth
That is, you get Template Haskell if you specify -fglasgow-exts. The
trouble is that if you don't know about TH, then the error messages can
be deeply strange, as Marc found.
Suggestion: if you want TH, you must specify -fth explicitly;
-fglasgow-exts won't imply it. That way any messages about staging will
only happen if you've explicitly asked for TH.
Any objections?
