According to TDPL, 5.9.1 "Pseudo Members and the @property Attribute", D allows
pseudo-member notation:
"if a.fun(b,c,d) is seen but fun is not a member of a's type, D rewrites that
as fun(a,b,c,d) and tries that as well."

Apparantly this is only true for arrays, and even for arrays it does not work
in some cases:

void gun(ref int[]) { }
void sun(ref int[], int v) { }

int[] global;
ref int[] fun() { return global; }
@property ref int[] funProp() { return global; }

void main() {
    gun(global);       // works
    sun(global, 0);    // works
    global.gun;        // works (but shouldn't ?)
    global.gun();      // works
    global.sun(0);     // works
    fun().gun;          // works (but shouldn't ?)
    fun().gun();        // works
    fun().sun(0);       // works
    funProp.gun;        // works (but shouldn't ?)
    funProp.gun();      // does not work but should
    funProp.sun(0);     // does not work but should
}
