delete was deprecated because it is memory unsafe (there may 
still be references to the memory). You can still use GC.free() 
to free the memory but it must only be used with care.

I feel if you are managing delete yourself you might as well 
manage allocation yourself too and take pressure off the GC. If 
you are sure you have only one reference and GC.free() is safe, 
Unique was probably a better choice anyway.
