Feature request: semantic highlighting of non-const ref/pointers arguments

[Yanpas]

It would be useful to distinguish between mutable and immutable function arguments. Currently implemented in Eclipse CDT.

E.g.:

void func(int a, int& b, const char* c, char* d);

// ...

int main(){
  func(a, b, c, d); // b and d should be italic/underlined
}
