I don't know how inescapable is your "requirement" to hide predefined "="
from "ALL" data types.  But here's something to consider:

How much will it cost over the life cycle to have maintenance programmers

replacing

   if (A = B) = True then

with

   if A = B then

only to (attempt to) compile and then change it back?

Plus the time wasted when initial programmers write

   if A = B then

out of habit and have to (attempt to) compile twice?

Of course, with GNAT you can change the compiler to accept the standard
form with your new type Bool  :-)
