traverse_

[Kazu Yamamoto (=?iso-2022-jp?B?GyRCOzNLXE9CSScbKEI=?=)]

Hi,

I have just installed GHC 7.10.1. I'm a little bit surprised because
'traverse_' is not exported from Prelude. But 'traverse' is exported.
Is this intentional?

I expected that I can forget xxxM, xxxM_, xxxA, and xxxA_ functions
with GHC 7.10.1. I want to use 'traverse_' instead of 'mapM_'.
