It works for me, but I'm curious - will compiler always recognize what
to call and I can avoid recursion and stack overflow or I shouldn't do
so?

No, not always. One out of two hundreds the compiler fails to recognize
the right call.
Jokes aside if you're not sure just use a templated function with `auto
ref` parameter.

Thank you for the hint. It works and even tests pass)
