Yes, as always there is a trade off. In almost no cases will 
functions take raw pointers, just like C# that has raw ponters 
you almost never use them other than in special cases.

Problems start to arise when when programs and shared libraries 
are compiled with different GCs. One thing I have personally 
noticed, having a pointer to the free function in the managed 
pointer type makes it very versatile. Even change GC in runtime 
becomes possible.

With managed pointers only, the world will open up for us to 
experiment with things like this.
