To add to that, if an allocator defines
`resolveInternalPointer` [0][1] you could be able to get the
original slice that was allocated (and then pass that to
`deallocate`, but not all allocators define
`resolveInternalPointer` and also even if they do define it,
they're not required to maintain complete book-keeping as doing
so could have bad performance implications (i.e. calling say
`a.resolveInternalPointer(a.allocate(10)[3 .. 6].ptr, result)`
can return `Ternary.unknown`.
