	That was actually a good discussion, much better than all of this 
OO and C++ stuff ;-).   

	Seriously, I was convinced at the end of that discussion that the 
restriction was necessary for "political" reasons. But stuff like this 
library makes me more sore about it. Ada could have been a better language.
Oh well.

	And the iterator stuff...

	It would be an interesting experimental addition to GNAT to support 
Pascalish function arguments, or even (as R. O'Keefe suggested) anonymous 
"downward closures" in function arguments.
