As far as I know (from a job application with the European Space Agency),
all the code for the Ariane system is written in Modula-2 (which, by any
definition, is a high-level language).

Modern optimizing compilers can do a _very_ good job. In many instances,
it'd take a top-flight programmer to do better at the assembler level
(as well as an awful lot more time).
