This is wrong code:


int[] foo() {
    int[] result;
    result.reserve = 5;
    foreach (item; result)
        result ~= r;
    return result;
}
enum r = foo();
void main() {}


dmd 2.066alpha gives an error message that I don't understand:

test.d(1,7): Error: function test2.foo circular dependency. Functions cannot be
interpreted while being compiled
test.d(8,13):        called from here: foo()
test.d(8,13):        called from here: foo()



If I remove the compile-time call it gives the right error message:


int[] foo() {
    int[] result;
    result.reserve = 5;
    foreach (item; result)
        result ~= r;
    return result;
}
//enum r = foo();
void main() {}



test.d(5,19): Error: undefined identifier r
