Well, Cray used to have an Ada (83, IIRC).

They also had a Lisp (Franz).

The idea was that the Lisp portion of a program would manage
the missile simulation, the Ada portion would direct the missile,
and the Fortran portion would report stresses, airflow etc.

The interesting part was that Lisp could change, e.g., the definition
of square root, in the middle of execution.  But that had better
not change the Fortran & Ada idea of arctangent!  It also probably
added some, ah, features, to the linker.  ;-)

It was a great idea, it just didn't work.  :-(
