Hello 👋,
I'm using PHP classes for storing configuration. Main DefaultConfig is versioned and second class Config is not versioned, where admin can alter some default configuration (eg change class constant API_KEY from null to some string).

https://phpstan.org/r/b9d95a54-6b62-4446-bf0c-6d0ea53bcef0

Various places in my code fails on Strict comparison using === between string and null will always evaluate to false.

I don't know, how to deal with this problem. Tried:

• updating treatPhpDocTypesAsCertain
• adding constant(s) into dynamicConstantNames:

  dynamicConstantNames:
      - Config::*
      - DefaultConfig::*
      - Config::API_KEY
      - DefaultConfig::API_KEY

It seems, that dynamicConstantNames works only for one type, because if I change default value from null to empty string '' and update code (https://phpstan.org/r/7e6bc8b4-ab43-423d-b181-f0bc08cf4c03), then PHPStan is happy (again, class constant must be set in dynamicConstantNames).

Is that intended behavior? I kind of don't like this workaround, but I guess I don't have better alternative than rewrite it like so.

Thanks in advance 👍
