This is something that has come out of a thread I have opened in D.learn.

In the thread qznc has answered me:

Operator precedence of "." is higher than unary minus.

That's right:


double foo(in double x) {
    assert (x >= 0);
    return x;
}
void main() {
    assert(-1.foo == -1);
}

Is this a good design of the operator precedences? Is this worth changing/fixing?

Bye,

From my POV this is good design. When I see:
assert(-1.foo == -1);
Is same for me as:
assert(-foo(1) == -1);
