Allow NULL

A questionnaire on how to implement the Allow NULL RFC.

Results from jrf (back)

Maintain lots of open source, not RFC voting power

How should PHP 9 work?
  1. NULL triggers a Fatal Error with strict_types=1, otherwise use coercion (like how integers can be coerced to a string).
  2. NULL triggers a Fatal Error for everyone, but update some parameters to explicitly allow NULL (e.g. `?string`).

Which of the following parameters should continue to Accept NULL, or should NULL trigger a Fatal Error?
