I don't remember for certain, but my recollection is that Ada 83 always 
implicitly converts the leaves of an expression tree; that is operations on 
universal types are only used for named numbers, operands of type 
conversions and the like. I don't think Ada 95 changed this significantly 
(the way the rules are presented was changed a lot, but that's not 
particularly important). I remember hearing the exact evaluation saw as 
well, but I don't think it was ever true other than in very limited cases.

                                  Randy (who did write an Ada 83 compiler).
