Agree. This is an important point in favor of Ada.

Yes. Machine code insertion capability would be essential. So too
would a set of 8051-specific packages that map to the architecture.
Such a set of packages could make Ada quite attractive if they were
to encapsulate the standard idioms of 8051 programming.

Ada-8051? HmmmMMMMMmmmmm. C'est possible? This would make a good
project for some graduate student doing a thesis in real-time embedded
software. Anyone advising such a student at the moment? Remember that
several commercially available Ada 83 compilers were originally
completed to satisfy the requirements for a master's degree. Ada-8051
might best be first developed this way.
