How to overload signal, zero or two paramters?

[ideaplus]

Overload signal, one or two parameters:

my_signal = Signal([int], [int, int])

I want to overload signal, zero or two parameters, but don't find any example. Or is this not supported?

Overload signal, zero or two parameters:

my_signal = Signal([], [int, int])
