No warning that a method being called on a class does not exist (even though the type's class is correct) #11353
Description
Bug report
Hello there,
Quite an edge case, but I thought it was still worth reporting. We're dynamically calling a method create on a class using $classFQCN::create(), and $classFQCN is properly typed as a union of multiple classes that should all have the create method. But if one of these class do not have the method, no warning is thrown, and an error happens at runtime.
Code snippet that reproduces the problem
https://phpstan.org/r/22f07bc0-a79d-44a4-92b6-e969d0e97e4f
Expected output
PHPStan should report an error like :
Cannot call "Test\C::create()" as the method does not exist.
Did PHPStan help you today? Did it make you happy in any way?
PHPStan is such a critical component when doing any kind of technical change (updating vendors, applying Rectors, refactorings...).
