It's possible that I'm mistaken, but to the best of my knowledge,
I am not familiar with the existence of such a feature, and it seems unlikely that it could exist (at least not in the purest sense or without clarity on its intended purpose).
In a perfect scenario, implementing something like this may pose challenges. Consider the possibility of an object being typed as a base instance but assigned a derived class instance, leading to ambiguity when navigating different code paths utilizing that typed variable/parameter/object field across instances of various classes. This complexity blurs the distinction between them. For example, if a function has a parameter typed as the base class and is called with both base and derived class instances, identifying the method’s usage becomes convoluted. And this is just a simple case.
If you narrow down your inquiry to cases where the method's host object bears annotations of the derived class type or where such typing is statically determinable throughout all pathways, then achieving this goal might be feasible.
