Pretty irrelevent to the newsgroup, but the Macquarie Dictionary (which I
believe to be the standard Australian dictionary ) has "initialise" 
and doesn't have "initialize".
      ("recognize" which you use above isn't in it either.)

     Good, I hope not to be caught again, but the "ise" comes so intuitively
that it might.  (After all, I had to put  with Ada.Finalization; at the top
so was aware of the problem.)
Actually "finalize" does make it into the Macquarie dictionary (although
as a somewhat secondary entry):
  finalise ... To put in final form; conclude, settle.  Also, finalize.

  The main point is that not syntactically distinguishing between overriding
declarations and new declarations is prone to undetected errors.
