## #117078 — G. P. B. — 2022-02-20T17:56:31+00:00

URL: https://externals.io/message/117078#117078

Hello internals,

As a follow up from the "Allow null as a stand-alone type" where the main
talking point was to also allow false to be used as a stand-alone type, a
new slightly modified RFC is now proposed:
https://wiki.php.net/rfc/null-false-standalone-types

The implementation has been updated to reflect the new RFC.

Best regards,

George P. Banyard

The new RFC has a link to implementation and a link to the previous RFC
(which has a link back to the new one) but I had to search for the original
*discussion*, so here it is: https://externals.io/message/116188

(+1 for me, with or without false)

Hello internals,

I'd like to open voting for this tomorrow.
I've expanded a bit the caveat about the specific Reflection change this
RFC introduces with handling of null|false compared to other T|null types.

If there are some final comments please let me know.

Best regards,
