The answer is no, but so what? This is like asking if there is a way to
define a function without using the function keyword, or whether there is
a way to have concurrent execution without using the task keyword.
Unchecked_Deallocation is for use in such contexts, why on earth worry
about whether you can do unchecked deallocations without using
Unchecked_Deallocation?
