And I highly recommend putting that line in your .ghci file.

There is controversy about whether MR is helpful in general.
It is on by default, so I just leave it that way, and it seems
to be fine.

But at the GHCi prompt, MR is definitely a nuisance.
Get rid of it there by using :set in your .ghci file.
