My experience with Starlark (buck2) is that it makes the whole system wildly complex and inscrutable.

No one actually knows how it works. It’s an undebuggable nightmare of macros. Everyone copy/pastes a few macros they know work. But one step off the beaten path and you’re doomed.

I hate code that looks like data but is infect code. Be data or be code. Don’t pretend to be both.

I tried adding support for Jai to public buck2. I didn’t even get close. I need static types and a debugger. Just make everything a Rust plugin.
