About playing with remote Node.js REPLs; I [recently](https://matteolandi.net/plan.html#day-2021-03-24) said: > I am sure there might be better and more idiomatic ways of dealing with this, but at least it unblocks me for now.

Alright, I think I figured a way to make [this](https://matteolandi.net/plan.html#day-2021-03-23) work by using a combination of `AsyncResoruce.bind` and `Function.prototype.bind`.
