Hi, what is the most primitive programming language (esolangs included) that you can think of or make up that could still be reasonably well1 supported by a language server (or similar piece of software)?

1 We have to draw a line somewhere, so I’d figure capabilities

  • highlight semantic errors
  • renaming stuff safely, that is:
    • without confirmation
    • without evaluating parts of the code
  • proper completion (not just best guess)
  • go to definition/show use

I appreciate your answers!
