13461 :: Negate "in" as in "not in"

• krakengore (orginal) [2025-10-15T17:01:52+02:00] view original

  I have this code:

  
  if t.kind in {tkKeyword, tkIdent}:
  Run

  Now i want to do:

  
  if t.kind not in {tkKeyword, tkIdent}:
  Run

  But i get:

  
  Error: expected: ':', but got: 'keyword not'
  Run

  I've tried searching in the manual or in example nim code but when i search for "not in" it basically finds everything and nothing at the same time :D

  The error message should probably say that…

  Yeah i really hope the new compiler will have improved messages

  Nah, the error messages are really good already. The occasional "why doesn't work X like in Python" wasn't a design criterion though, much like Python's error messages were never designed for former Modula 3 programmers.

  Well, a little bit more context wouldn't hurt, and probably help llm agents as well...

  Yeah, or we wait for 2 days until the LLMs catch up...

  GPT 5 with Extended Thinking can actually handle very complex queries about Nim now, I've been thoroughly impressed.
