I wonder why rector is not able to infer the string return type

[samsonasik]

PHPStan seems detect variable $style in last rerun as error type, see https://phpstan.org/r/ea1c7a84-2be8-44bf-913d-f1b8e0db64dd

@staabm I created PHPStan issue at phpstan/phpstan#9855

Thx. Seems its a autoloading issue then. I need to check class loading rules.

But I still got an idea from this conversation. Maybe we can have a rector which replaces the variable return with a constant value return when phpstan is able to narrow the variable type to a single constant value?

I discussed with Ondre, it seems the type when class and method exists, it got ConstantStringType, that may need to be checked.
