Deterministic Finalization III - Benefits, part 1

Of course the C++ way to handle this is a smart pointer:
auto_gcptr<Font> font = gcnew Font();

then when the autoptr goes out of scope it will be destructed.

The implementation of auto_gcptr should be pretty easy but it would be nice to have this in the microsoft extensions to std.

Now that is a big improvement over nesting usings to Dispose of a number of elements. and we get deterministic finalization by combining the scoped destructor with the Dispose pattern

Why not allow the compiler to automatically insert the % when calling a function that expects a handle.

Having to write foo(%f1) complicates the abstraction needlessly. The compiler knows that f1 _is_ a handle in reality, so it could do this without any intervention from the programmer.

I didn't want to give the impression that I was suggesting the use of nesting "usings" - our solution to handling disposable items is to have ref types on the stack.

As to not allowing the compiler to insert the %, it comes back to the copy constructor. As we are going to have copy constructors for ref types, it will be possible to have a foo(R r) function signature.

It would confuse matters to have this sort of implicit boxing conversion for ref types as well.
