A modern programming language that makes developers happier.

kotlinlang

I'm curious, has anyone ever tried anything like this in a non-trivial Kotlin application?

I think that once multiple receivers come out, this technique will sort of be moot -- but for now it seems to me like a nice way of emulating them with just a single receiver parameter.

This reminds me a lot of "mtl-style" programming in Haskell.

this technique has been discussed several times but IMO is best to wait for multiple context receivers.

creating the God object is not always easy if some of your dependencies are classes or interfaces you don’t have control over.
