Hi everyone,
Thanks for all your feedback so far.
Previously I asked for "more precise" feedback, which has been
interpreted as evidence backed feedback. That's not what I meant.
My fault for not being clearer.
Your opinions without any justifications are welcome, but I need
precision.
The PEP states:
"""
Reference Implementation
None, as yet. This will be implemented in CPython, once the PEP has been
accepted.
"""
A Python that implements PEP 611 might have advantages and
disadvantages. The disadvantages we can clearly see: Things that were
possible before will no longer be possible. But whether the PEP has any
advantages is unknown. So an implementation might have to come first.

Almost any performance gain, even 0.1% is worth the, IMO, slight
inconvenience of 1 million limits.
The reason I believe this is that a 0.1% speedup benefits all Python
applications and libraries everywhere and forever, whereas the
inconvenience will be felt by a handful of developers, very rarely.
A 0.1% performance gain means that a script that runs for an hour will
finish 4 seconds earlier.

Servus,
Walter
