Either ResizableBooleanArray has been significantly refactored since this ticket was submitted last year (it has been), or the ticket was never true in the first place (possibly also true). In the current implementation of ResizableBooleanArray and FixedBooleanArray, each bit of information is stored as a single bit of an unsigned char (Parrot_UInt1).
