Hi everyone
We recently received a feature request to allow reflection of global
constants, primarily to check whether they are deprecated.
https://github.com/php/php-src/issues/13570
I created a simple PR to introduce a minimal `ReflectionConstant` class.
https://github.com/php/php-src/pull/13669
If there are no objections, I'd like to merge this PR in a few days.
