I am sure that a number of other Arcadia people will respond, but ...

Arcadia has consistently supported multi-language heterogeneity
as one of its goals.  So much of the software is in Ada, much is
in C, and some is in C++.  At times, we have also used Prolog and Lisp.

With respect to Ada and C specifically, we have attempted to
provide Ada interfaces to all of the C code to avoid producing
systems that could not interoperate.

Additionally, the Arcadia environment toolkit is organized primarily
as object services communicating via remote procedure call.
Interfaces to those services are, as a rule, provided in both Ada and C.
