Kyo in Clojure

[fwbrasil]

While #871 is meant to explore exposing fine-grained effect tracking in TypeScript and #872 explores constrained effect tracking in Java, I've been wondering if it'd be possible to provide a good experience with algebraic effects in a dynamically-typed language.

The existence of untracked algebraic effects in OCaml indicates that it might be possible:

Unlike languages such as Eff and Koka, effect handlers in OCaml do not provide effect safety; the compiler does not statically ensure that all the effects performed by the program are handled. If effects do not have a matching handler, then an Effect.Unhandled exception is raised at the point of the corresponding perform

Given Clojure's focus on FP, it seems a good target for this exploration.
