Why so limited? Like, why disallow objects completely? That feels
like a big step backward for PHP. Any why not computed constants?
(Assuming they stay constant throughout the process lifetime)

I'll be honest, I'm not a big fan of code-generation. I find it
introduces complexity and it's not needed here. Lots of languages
manage to put together a stable API without resorting to code
generators.
