New description:
The error message on a misplaced DEPRECATED pragma is less than helpful.
Note that it was the latter of these that bit me.
'''% cat Main.hs'''
{{{
module Main where
import Foo.Bar
main = return ()
}}}
'''% cat Foo/Bar.hs'''
{{{
{-# DEPRECATED foo "bar" #-}
module Foo.Bar (foo) where
foo = undefined
}}}
'''% ghc -c Foo/Bar.hs'''
Foo/Bar.hs:4:0: parse error on input `module'
'''% ghc --make Main.hs'''
Foo/Bar.hs:1:0: file name does not match module name `Main'
