It is sometimes very slightly annoying that misspelling a pragma will mean that it is silently ignored. Oh well. I've typed:

{-# OPITONS -fglasgow-exts #-} or {- # OPTIONS -fglasgow-exts #-}

many times. I usually expect that GHC knows what I'm thinking, and am surprised when it doesn't get it right ;)

You probably don't want the warning on by default, since it is a Feature that unrecognised pragmas are ignored by default. I'd add the warning, except that it's not trivial - the pragmas are thrown away in the lexer, and the monad doesn't have a way to collect up warnings. I'll put it on the task list though.
