Last year, Nuno Maduro and I put together an RFC for combining the

due to concerns over the performance impact, which Nuno and I didn't
have bandwidth to resolve.
Arnaud Le Blanc has now picked up the flag with an improved
implementation that includes benchmarks showing an effectively net-zero
performance impact, aka, good news as it avoids over-capturing.
The RFC has therefore been overhauled accordingly and is now ready for
consideration.

The conversation has died down, so we'll be opening the vote for this tomorrow.
Two changes of note since the discussion started:
* The option to mix explicit capture and implicit capture has been removed as
too confusing/unpredictable. Either trust the engine to capture the right
things (the new syntax proposed here) or explicitly list everything (the
existing syntax we've had since 5.3.)
* We added a section discussing the `use(*)` syntax alternative, and why it
wasn't, er, used. (Pun only sort of intended.)

Hi,
Would it be an option to include a "Future scope" with the features:
- Explicit capture that list only the variables to be captured by value
or reference, nothing else.
- Extending the traditional anonymous function with use(*) for capturing
everything.
Anyway, hope this passes for PHP 8.2!
