--------------------------+-------------------------------------------------
Here is a conceived example that illustrates the issue.
File {{{Foo.hs}}} is changed after it's content has been read in the
Haskell pre-processor phase.
{{{
#!/bin/bash
#
# file preprocess.sh
#
cat $2 > $3
sleep 1
touch $1
}}}
{{{
-- file Foo.hs
{-# OPTIONS_GHC -F -pgmF ./preprocess.sh #-}
module Foo where
}}}
{{{
$ ghci Foo.hs
*Foo> :reload
}}}
Expected result: Foo.hs is recompiled on :reload
Actual result: Nothing is recompiled on :reload
