If this means what I think, it means put() cannot be memory safe. 
Making an array from a stack variable and passing it around cannot be 
safe unless you can trust this reference won't escape the scope of the 
delegate you're calling (and there's no way to enforce that for dynamic 
arrays). To be safe, all you can do is copy the element on the heap. Am 
I wrong?
