Yeah... "static assert(void.sizeof == 1);" passes :/

So in any case, long story short:
"void[]": This is an un-typed buffer, pointing to a memory 
location that starts at .ptr, and is .length bytes in length.

Also, as far as the GC is concerned, "void" is a type that should 
be scanned (whether or not the data originally allocated was 
marked as such is another issue).
