GHCi erroneously unloads modules after a failed :reload
Say you have three modules:
module Main where
import Foo
import Bar
module Foo where
module Bar where
And you run the following in GHCi
:
:load Main
:! echo '"' >> Bar.hs # alter Bar in such a way that it fails to compile
:reload
What I expect to have happened is that Bar
fails to compile and so does Main
(because Main
imports Bar
), thus Bar
and Main
should get unloaded. So in the end Foo
should be the only module left loaded.
What I've observed is that not only do Bar
and Main
get unloaded, but Foo
does too! Yet Foo
should not get unloaded because it has been altered.
