 Ghci (in the default config) wants to show me all the modules that are
 currently loaded.

 If I have a great many of these (think: hundreds) then this is
 impractical, because I have to scroll back to see what actually interests
 me (output of last command).

 I can change the prompt (`:set prompt "> "`), but I don't see how to
 switch off the display of all module names in `:r` command.

 I have to scroll back (several screenfulls) to even find out whether the
 reload was successful, since the status (OK/Failed) is at the very
 beginning - and the reason for the Failure is before that.

 Cf. https://mail.haskell.org/pipermail/haskell-cafe/2017-May/126983.html
 (but there was no reaction)
