The first function will be used. Shouldn't the template argument (T :
T[]) make the compiler pick the second one?
There is also template constraints which may be useful:

I also forgot to mention that the overloadedFunction is used in a

Obviously the second should be used when the parameter is a slice of any
type, and the first should be used in other cases.
