This limits you to exactly 5 parameters, which means, among
other things, that the call as written (with Y commented out)
won't compile. The array notation allows for variable-length
I would have loved to see Ada introduce a type-safe version
of variable-length parameter lists, but that's an entirely
different kettle of syntactic/semantic fish...
By the way, we don't know what type Z is, so we don't know
for sure that either Y+Z or Y-Z will be <= Y.
Of course, a poor coder may also have redefined "+" or "-"
for float, to do some special-purpose coding. After all,
code is so much easier to read with user-defined infix
