Well, I somewhat find it strange to have to say "from mercurial" in a
module that's *inside* mercurial already...

But then, Python is not my home turf [1] - despite me having sent quite
a couple of patches for Mercurial already.

I'd clearly prefer keeping things easy for what the *real* needs are,
than trying to solve a negligible, dubious (non-)problem (helping newbies).

So what do you propose specifically? After all, the "from mercurial"
import of base85 here broke setup.py.

Keeping things correct and fast seems clearly more important to me than
trying to making newbies happy.
