Bleeding edge + strict rules in v1.12.11 suggests comparing DateTime objects via strict comparison.

Bug report

Dates in DateTime objects can be compared only using the loose == operator, however when I switched bleeding edge on (on top of strict rules), phpstan started suggesting to compare DateTime objects via strict === comparison, which compares the objects themselves, instead of dates.

Code snippet that reproduces the problem

https://phpstan.org/r/2c276792-c7f0-41b1-bde7-2dc8de08adcb

Expected output

I think phpstan should not suggest strict comparison using === for DateTime and other date objects.

Did PHPStan help you today? Did it make you happy in any way?

No response

Just FYI there are custom rules to deny the strict comparison: https://github.com/shipmonk-rnd/phpstan-rules?tab=readme-ov-file#forbididenticalclasscomparison
