Would like to see ref and out required for function calls

People debugging large bodies of code should not be required to 
hover the mouse over each and every function parameter for a 
second to properly understand structure. People using non-tooltip 
text editors have an even harder time.

I think you're missing the point. This code:

     int* x;
     foo(&x);

at least tells you there's a _potential_ x is being manipulated 
rather than just used. We don't need full insight into what's 
going on, just a helpful hint which narrows the potential 
culprits when debugging.

If fact, it would nice if even reference types where required to 
follow similar "is modified in function" semantics, and I have 
ideas about that, but I'm not going there right now...
