You can improve it by telling where it went wrong, so by having a dialog. But it's so freaking frustrating that you may as well do the job yourself – works better if there are some tests defined, at least it can converge on a solution by bumping into walls.

'AI' Sucks the Joy Out of Programming
I’ve used spicy auto-complete, as well as agents running in my IDE, in my CLI, or on GitHub’s server-side. I’ve been experimenting enough with LLM/AI-driven programming to have an opinion on it. And i...

A type-class instance is just a dictionary of functions, indeed, and this is a common tactic, even in Haskell, because in Haskell type-class instances aren't just values, and that can be limiting.
But the super-power of type-classes is that you can derive their instances.

Type-classes are generic interfaces. You're referring to OOP subtyping, which is powerful, and I can ask the same question in reverse (i.e., why do you need OOP, when you could …).
Type-classes work better w/ functions + ideology (note that I love OOP, too):

(Taking “European” out of the sentence)
What if “leaders” do understand how E2EE works?
Consider this: the state is always expanding, it's never shrinking of its own accord. It is in the direct interest of “leaders” to have more power.
