FYI: the current name for this is ACATS: Ada Conformity Assessment Test
Suite.

What does "in" mean here?  Is "rust" modifying "language" or "compiler"
in this case?  As was stated, that's a significant difference.

It's a very different situation.  Ada was a standardized language via
a very formal process.  And it was a very different time.
