I think this code is correct:


@property int[] foo() {
    return [1, 2];
}
int[] bar(int[] a) {
    return a;
}
void main() {
    bar(foo); // OK
    foo.bar(); // line 9, Error
}



But DMD 2.057head gives:
test.d(9): Error: function expected before (), not bar(foo()) of type int[]


This makes the usage of D language less uniform, because code like this is
refused (and sometimes you can't replace an array attribute by a @property
getter because of this):

auto sortedAKeys = a.keys.sort(); // error
