You mean ref, not inout.

And in C++ it is again impossible because the ref parameter is a reference.

I've heard this proposal before. It is an interesting idea but I've been 
coding in C and C++ for years. I have never had an issue related to this 
topic. I always knew what a function call did. I don't remember a single 
bug that was caused by this.

I don't even prepend "ptr" to pointer variable names.

So I don't see the benefit.
