I think it would be somewhat hard to make the parser to split usages into 
those categories...

int foo=0; // declaration of foo
foo=42;    // write to foo
foo++;     // write? arguably it's reading too
aaa(foo);  // what is this?

int* bar = &foo; // or this?

MyClass obj; // declaration of obj
obj.method(); // what is this doing with obj?
