It says:


"The overflow is sticky, meaning a sequence of operations can 
be done
and overflow need only be checked at the end."

But how can I make multiple operations? I can only put 2 
values in the
function.

import core.checkedint;

void main() {
    bool overflowed;
    auto result = adds(int.max, 1, overflowed); // this 
overflows
    adds(1, 2, overflowed);     // this does not reset the flag

    assert(overflowed);
}

wow, this I don't understand at all, how do those two operations 
connected to each other? By the bool value?
