#6007: ghci: Importing specific non-existent names from a module breaks later
imports

------------------------------+---------------------------------------------
At the ghci prompt, attempting to import specific non-existent names from
a module breaks any future import attempts, causing them to fail with the
same error message that the original import failed with (in addition to
any error message they generate themselves). For example:
{{{
Prelude> import System.IO(foo)
<interactive>:1:18: Module `System.IO' does not export `foo'
Prelude> import Control.Monad.Error
<interactive>:1:18: Module `System.IO' does not export `foo'
}}}
Or compounding the problem:
{{{
Prelude> import System.IO(foo)
<interactive>:1:18: Module `System.IO' does not export `foo'
Prelude> import Control.Monad.Error(foo)
<interactive>:1:18: Module `System.IO' does not export `foo'
<interactive>:1:28:
Module `Control.Monad.Error' does not export `foo'
Prelude> import Control.Monad.Error
<interactive>:1:18: Module `System.IO' does not export `foo'
}}}
