The trouble is you can't tell that you might have to check the function
declaration by looking at the call.  f(a, &b) tells me I might want to
look at f's declaration to see if the second parameter is a pointer to
const or not, but f(a, b) does not.  Either a or b might be modified and
I have to check f's declaration every time.
