Coroutines and lambdas are orthogonal features. if the language supports it, a lambda can be a coroutine. Arguing that one will replace the other strikes me as nonsensical.

And I don't hate gdscript, I just think it's incredibly half-baked and feels very immature. It's understandable that they only have limited resources, but that doesn't make my experience with it better.

Languages matter an incredible amount because of how heavily they influence system design. You can design an awful system in any language, but if you have to treat everything like a nail because you only have a hammer, you're bound to make a lot of awful decisions.

Edit: also, good IDE support really is incredibly helpful for working on larger projects

Im thinking of both lambdas and coroutines as techniques for asynchronous programming - like the 'complete' callback for a network call, for instance.

For functional programming, yeah there's no equivalent to a lambda in gdscript, but again, I think it's exceptionally well suited for the kinds of things you do in typical, run of the mill, game dev.
