What about being able to map chars or sequence or objects back onto
allocated memory? Then Al could allocate some memory, point a sequential
list of chars onto it, and then map a sequence onto it. Assuming, of course,
when he assigns a value to the sequence, the char type checking is also
performed (because the was value changed when the overlying sequence
was changed).
