[Users] param.ccl: accessing non-restricted variables of another thorn?

[David Rideout]

I see.  You can just put "restricted:" at the top of your param.ccl.
I rarely have private parameters.

It is better practice to communicate via the CCL / CCT when possible,
so that Cactus is (at least in principle) aware of implementations'
interdependencies.

Cheers,
David
