OK. What about refcounting with smart pointers?

This form of GC actually works against your determinism goal. It simply is a
poor form of GC, can't handle cycles, and has unpredictable execution times.

A "real" GC smoothes out the collection costs.

But your main points of needing scoped-based resource control I indeed agree
with. My thing is convenience: sometimes that is simple wrappers with
destructors to cleanup after any possible scope exit, sometimes that is the
"WithResource" wrapper function pattern.
