I can't speak about the entire Ada community. JPL used Ada -- reluctantly
at first -- for the 26 processors on the Cassini spacecraft (nearly to
Saturn now) that are our responsibility. By coincidence, not design, there
are another 26 processors buried in instruments that were provided by others.
I don't know what language was used for their code.
Long after Ada was declared dead, I went to a Southern California "TriAda"
conference. There were well over 3000 people attending.
Ada includes many extremely good and well-implemented features. I have
modeled several of my suggestions for extensions to Fortran on features
in Ada that accomplish the ends I want to achieve. For example, the
Modules TR 19767 was originally modeled on Ada's distinction between
package spec and package body. I generalized the design, and then realized
that the generalization was in exactly the direction the Ada committee
went when they introduced "private child units" in 1995.
