The second part above is so garbled that I can't guess how to respond to it.
The first part is easy, one camp says unary "+" doesn't have a (useful)
mathematical meaning, so let's ignore that meaning and use the operator for
conversions. The other camp says that unary "+" has a (useless) mathematical
meaning that should be left alone. Because of the dynamics of the Ada
standards process, neither camp ever gets to lead and the net effect is that
we never get *any* conversion operator. Which we've needed from day 1, IMHO.
Randy.
