EMAS (https://en.wikipedia.org/wiki/Edinburgh_Multiple_Access_System) had 
an almost identical system, called its Scientific Jobber. It was a 
separate subsystem that once again compiled short program to memorry and 
ran very fast. It had extensive checking including uninitialised 
variables and bounds checking. It supported three languages - Algol-60, 
FORTRAN-IV (and later), and IMP (the system implementation language).

I worked on the actual operating system for about 8 years, including 
porting it to XA architecture.
