Great news and thank you to all the developers! I carefully read
through the notes and look forward to using the new array methods
and also the management operators.
One question to everyone though, what use cases do you see for the
IsManagedType intrinsic?
Mainly generics. E.g. when dealing with arrays you can simply do a
Move() for non managed types, while for managed types you need to do
it by element.
Not just that, consider e.g. something like tlist<t> if "T" requires
management, a tlist<t>.clear must finalize all elements. If it is a pure
value type, it doesn't, and can skip the whole loop. Afaik fcl-stl has
some examples of that.
