In Ada, when building boolean expressions you must put ANDs and ORs (and
OR ELSES, etc) in parents IF you use them in mixed combination.

Ex.  (A and B or C) -- is not legal.  You must write it as...
     (A and (B or C))

So the question is -- WHY?

Does this remove some semantic ambiguity?  Or is it just the "Ada style!"

Thanks for any responses...
