I recently had a conversation with a person from Boeing who advised me that their comparison study revealed the Ada compilers to be slower running a set of benchmarks than code in C++. I am told it is an internal document, so I was unable to get access to it for my own tests. Meanwhile, it is certainly the case that C++ and Fortran are not inherently faster than Ada. In "Who Killed Roger Rabbit," the sensuous cartooned Lady named Jessica says, "I'm not bad. I'm just drawn that way." Ada says, "I'm not slow. I'm just implemented that way." Richard Riehle
