Just a clarification:

You missed the part that says "Optionally, can compile to efficient
native code." Here, efficient means "at least as good as C".

Nowadays, thanks to projects like LLVM, it is easy to roll an
industrial-grade optimizing compiler if the language runtime
requirements are not too far from C. It is straightforward to design a
language that equals C in speed of execution and that is way more

Actually, some of those languages often compile applications to code
that is faster than their C counterpart, as they are more
