Replying to [comment:19 kcrisman]:
> I realized another question. I can't build a branch right now to check
this, but I believe that in the past the `c` and friends were not only
confusing, they didn't actually correspond to any Sage variable. So now
we have it that there is unlikely collision, but even then we still have
`_C` and friends not corresponding to any Sage variable
Uh ... as soon as these make it back in sage there are symbolic variable
objects that represent them. They are full-blown pynac objects right then.

That has never been a requirement for objects to "exist" in sage. I don't
think this is an issue at all. The objects can be accessed via `SR("_C")`
as usual, and in fact if the user does {{{_C=var("_C")}}} or toplevel
`var("_C")` he/she can have the object bound. We should absolutely not
mess with namespaces during runtime. We ''might'' prebind `_C` etc. if
someone thinks it's too difficult for users otherwise.
