That could work - could be interesting to experiment with.

In Delphi that would be the

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?

Just want to clarify something... if a type is managed, can it
be safely
typecast to a pointer in all instances and on all platforms? (The
purpose being so if I wanted to swap two items, so there's no
overall
change in the reference counters, I can simply swap the
pointers...
there's no dereferencing involved!)
No, managed does not automatically mean that it's a Pointer based
type. Records with management operators, Variants and Windows
WideString are managed as well.
