Even the IfCtx "tricks" and stuff like /u/Noughtmare's post don't resolve the constraints at runtime. The constraints are still resolved statically, you just carry around a (constant) token that indicates how compile-time resolution went.

How do I define this super-unsafe type class (not internally consistent at all 😱)

Where's more discussion of the designs of effect systems?

Languages such as Koka only support algebraic effects, not scoping operations such as catch and listen. The Effect Handlers in Scope paper introduces scoping operations, which lead to the Haskell libraries fused-effects and polysemy, but they turned out to have some weird semantics. eff is her effort to fix that.
