I'm not sure I understand what the intended use case here is. Can you maybe
show an example of where this would be useful / how it would be used?

Note that the parameter type may change even with strict_types
(int->float). Further note that parameter values may change in the body of
the function, so you don't have a guarantee that it's the original value in
any case.

Thanks,
Nikita
