<p>Well that spoils that idea! Is there any way to determine if
it's pointer-based so you can swap references instead of going
through the whole penalty of creating and destroying temporary
objects?</p>

want to clarify something... if a type is managed, can
it be safely <br>
typecast to a pointer in all instances and on all

there's no dereferencing involved!)<br>
