I would personally rather see repeatM and repeatM_ like the
replicateM/replicateM_ pair already in Control.Monad.
I implement them like this:
repeatM = sequence . repeat
repeatM_ = sequence_ . repeat
Google CodeSearch tells me it's the way replicateM was implemented too:
Btw, i hope it is ok to give my opinion on this. Im asking since im not
a library developer or anything just a normal programmer.
