IIUC, it’s not at their limit, but making any changes would be extremely annoying.

The code generated by BC’s JIT could have been improved by better register allocation. But the main limitations on its performance is the implementation of continuations and the calling convention. Those things could have been improved (mostly by imitating Chez Scheme’s implementation).

Agreed.

It was pretty optimized. It would have been possible to turn BC into a better compiler and a better runtime system, but that would have required writing a lot of code that would have done much of what Chez is doing already now.

Check the “copy” and “show hidden lines” feature in the Rust docs:

There’s a feature request that asks for the copy button somewhere

Is anyone here using Nix or Guix? I’m curious about the two systems/managers and it would be interesting to hear a Racketeer’s assessment of either
