Darn, I can't edit my original post.

But, the example that you've provided is very simple, but when it comes to types in Ada, it's a vast subject and type Temp is range -40 .. 40; does not do it justice.  There is so much more to this than that and to have someone new to try to untangle the different concepts and make sense of them will only have them abandon Ada.
