Comment(by simonpj):
I argue for a command because it only makes sense in GHCi. What would it
mean to have
{{{
{-# OPTIONS_GHC -interactive-print=foo #-}
module M where ..
{-# OPTIONS_GHC -interactive-print=bar#-}
module N where ...
}}}
Now load M and N into GHCi. What print to use? GHC's flags almost all
affect one particular module. This doesn't: it affects the REPL, so we
should put it in the REPL. Just like `:set prompt` or `:set editor`.
(Ian's right; `:set prettyprint` would be the right thing.)
