The restricted integers supported by Ada are so simple and obvious that it's amazing so few other languages have adopted them.

Right, I forgot that Ada allowed since its introduction to declare integers of arbitrary range and the compiler adds runtime checks to throw an exception on out-of-range operations. Do modern Ada compilers optimize those range checks using the CPU's overflow control flags when the range is a full machine word?

You can do the same thing in any language that supports operator overloading. Write your own setters and you can restrict any type in any way you want.
