   4. The correct syntax for deleting an array is "delete [] p;".  The former
   syntax, in which an expression within the brackets was required to give the
   number of elements in the array being deleted, is now officially an
   anachronism.  [Implemented.]

Mr. Hill & Roger:  forget what I said before.  Since "operator new(..)"
and "operator delete (..)" can be provided by the user, I don't see
how it is *possible* for the language to implement this.  (For those
who missed the verbal conversation) The issue is: if you are deleting
an array of objects with destructors, how does C++ know how many
destructors to invoke?  I'll investigate in the A.R.M. (The new
Annotated Reference Manual by Ellis & Stroustrup).  Is this an issue
for us (i.e., do PrimArrays need it?)
