Don't you wonder why should it be this way? Shouldn't safer code be more
efficient?

I prefer to think that Ada has an emphasis on *semantics*, which, when
properly defined allows a deeper optimization and safer programming.

The major problem of C++ is not its awful syntax. It is that a "normal"
programmer reading and writing C++ code does not really understand what
this code does. It is like X'Access attribute in Ada, you newer know what
surprises accessibility checks will give. You have some little "theory" of
what it could be, but this theory is customary wrong, and you have neither
time nor desire to verify it. In C++ most of such pet "theories" are wrong.
Ada is designed to be more friendly...
