[...] These are called dynamic variables in Lisp. They're only really useful as a way of doing things like I/O redirection, and you can just shallow-bind them to make them fast (but then they need to be per-thread as well, and pushing a bindin…

fluid-let is a famous Scheme imitation of dynamic variables. SRFI-15: https://srfi.schemers.org/srfi-15/srfi-15.html [1999]

I apologize for being ambiguous. You wouldn't gain the benefits of ATS by interfacing with its C bindings from C. You would gain safety and security in interfacing with unsafe C on the ATS side through the ATS type system. I was speaking about interfacing in the opposite direction.

I think that having really strong interoperability requires both directions, but the being called from C is the one that is more restrictive on fancy types.
