I wish there was a type-checked equivalent to what move does. copy creates a new 
array, and I don't want to do that: I already have a big block of memory 
reserved in the dynarray. I just want to move some data into that space -- 
sometimes only a part of it. Is there any alternative?

It would be nice if move would give a compiler warning or note if it receives a 
pointer-pointer. I guess that would require move doing type-checking... but at 
compile-time, is there anything wrong with move doing such a type-check and 
issuing a warning?
