What does static have to do with anything? Whether the member function is static or not, if it's a getter or a setter that returns by ref, it has no parameters, and if it's a setter that does not return by ref it has one parameter. If it's a free function, then a getter has zero parameters and is used by itself, or it has one parameter and is used with UFCS, and if it's a setter, then it either has one parameter if it's used without UFCS and two if it's used with UFCS. static has no effect on any of this.

$(LI $(D @property) functions cannot have variadic parameters.)
$(LI For the expression $(D typeof(exp)) where $(D exp) is an $(D @property) function,
the type is the return type of the function, rather than the type of the function.)
