Ha! This facility once redounded to my advantage when rehosting airborne Ad=
a 83 code for a full scale flight simulator in Ada 95. Package Calendar had=
 to be replaced by a simulated time calendar. Rather than searching the mil=
lions of lines of code and exchanging Calender by Sim_Calendar, I only had =
to declare
package Calendar renames Sim_Calendar;
(I know I was lucky because the airborne code used Ada 83 and I could use n=
ewer Ada generations.)
