Why is this in “Core Development” and not “Ideas”? It would be a big breaking change for many users (e.g. anyone who ever uses scripts to write Number Theory or Cryptography) and would presumably require a PEP?
I’ll note that limiting integers to be capped by default to printing 4,300 digits (approx 14,284 bits) without prior announcement caused significant backlash: Int/str conversions broken in latest Python bugfix releases.
Or am I misunderstanding, and this is an internal implementation detail that affects C code and not Python code?
Edit: Apologies, reading again, this is almost certainly “CPython implelentation integer” and not “Python Integers”. I hope you appreciate why I found the termanology confusing.
