Sorry, accidentally hit commit too early. Try again:
There should be a warning about unchecked use of pointers in C++. For example:
void f(T * const x) {
x->something... // x might be 0, warn.
}
void f(T * const x) {
if (x) x->something... // this is OK, no need to warn
}
This warning would help to find places where the programmer has made a very
common kind of error; he has made the function take a pointer parameter when he
should have used a reference instead.
