c-cube mentioned a couple, here's another: algebraic effects, or to put it another way, 'resumable exceptions'. Go doesn't even have exceptions natively. The level of indirection this alone would introduce to handle it, would make it an extremely leaky abstraction.

Beware that in your naked grab for users, you don't disappoint them and end up actually driving them away.

Eh just through in a sum type. Unwinding or other runtime support for exceptions is highly overrated in my mind.

What's really dank is doing https://www.ccs.neu.edu/home/shivers/papers/mrlc-jfp.pdf i.e. multiple return pointers. This way you can do the Rust Result (Either Monad) thing without branching.
