I'm half and half on this PR. These aliases are documented as deprecated, but they have never received a proper deprecated pragma. I'd rather see their use removed and their definitions have a pragma attached in a minor release. We can then remove them definitively in a major release.

@eborden Sure, I'll prepare something.

I'll bring this PR in a pretty state soon.

All good, just let me know when it is ready for review.

@eborden let's land #205 first. I am not in a hurry :-)

@eborden okay, I am all set. But there's no hurry, let the deprecations soak into the packages out there first. Anyway, I don't expect bad merge churn with these changes.

@kazu-yamamoto Could be time to unearth this PR.

@eborden OK.

I will merge this with rebasing to make the history linear.

Done.
