Comment(by igloo):
You can't do this:
{{{
module Q (foo) where
foo :: ()
foo = ()
}}}
{{{
module W (foo) where
import Q
{-# DEPRECATED foo "Some reason" #-}
}}}
{{{
$ ghc --make W.hs
[1 of 2] Compiling Q ( Q.hs, Q.o )
[2 of 2] Compiling W ( W.hs, W.o )
W.hs:6:16:
The deprecation for `foo' lacks an accompanying binding
(You cannot give a deprecation for an imported value)
}}}
