Wrong duplication detection on function overrides?

[satanTime]

Hi everybody,

I met an interesting case. There are several different function overrides which are detected as a duplication, but I don't see a way how to solve them.

The idea is that the 3rd argument specifies the return generic type, every type is different.

Might you help me to understand how this could be fixed?

Thank you in advance.
