programs." Any idea how much Python is used for flight control systems
in commercial
transport aircraft or jet fighters? How about ballistic missile launch
and guidance systems?

to compete with SPARK Ada or even Ada at the highest level of that

The important question is this: why do I waste my time with bozos like
