While useful, I think its ubiquity to simplicity ratio is not
high enough to justify either depending on MissingH
just for that, or adding it to a base library.

However, if your personal style makes this so
ubiquitous as to override its simplicity, go ahead
and upload it to Hackage, perhaps others will
also benefit.
