I strongly object to this. There are many optional features in
Ada, including for example the entire information systems
annex, or complex arithmetic in annex G. It is absolutely
perfectly reasonable to write Ada programs using these
optional features providing that you have a clear understanding
of the requirements you place on the Ada compiler as you do it.

More accurately, he said that it would not be added unless
there was significant customer demand -- there is none!

There is nothing bad about Ada code that depends on optional
features of Ada. Do you really think that any Ada code that
uses tasking priorities is bad? Of course not!!! It is just
that such code requires an Ada compiler that implements this
optional Ada feature.

They were quite familiar, they were unconvinced (perhaps they
were unaware of any significant examples of large mission
critical real time systems implemented in Modula-3 that they
found convincing :-) :-)
