i had to change the generic type names of this function from A B C D to something else, as identity() and identity2() are also using A and B as generic type names, which made the type resolution fail. Been trying to dig into it a bit but as for why i'm really not sure right now,

Also improves the
array_mapreturn type extension to be smarter about generic callables, specifically for single argument constant arrays.This improves the situation of phpstan/phpstan#10685 but i hesitate to say it solves it, there are some underlying issues that i'll add to the relevant test locations on this pr
