miniblog.

Doing another iteration on my diagnostics display. I'm reasonably happy with the bold highlighting within the error message. I'm not sure about the colour on Warning and Error though. It gives the output some visual structure, but arguably the message itself is more important.

Lisp is the only language I've seen where it's idiomatic to have some locals scoped to the *middle* of a function. It's a consequence of let blocks. It's neat, but I rarely miss it elsewhere. I'm happy with "scoped from here to the end of the block" in e.g. C or Rust.

I've never seen a JIT with an "eject" option. If I'm happy with the steady-state performance of my system, I'd rather disable the JIT and lose additional optimisation in favour of removing the tracing overhead. Do any languages offer this?
