     I can.  One reads about datatypes for a language, and the first
thing that comes to mind is what values is it a collection of.  Then,
comes operations.

     One does not expect common things to be redefined without notice.
That is what the octal notation does.  There is also a good reason for
using leading zeroes (alignment).

     Certainly.
