It would be great if it had a proper IDE. That's the only major hurdle to the success of this platform.

LSP support is pretty good for Elixir. Most of the actions are supported and it's pretty fast. There's definitely not as much drive for IDE tools as I'd like to see out of the core team/Elixir community but pretty good LSP support works in almost any IDE.

Yeah, but integrating the IDE with dialyzer is a pita. And if you don’t have that, it’s not a “proper” language
