There are features of all languages that some might consider as
"unusable" for satellites. In fact I know from experience that in the
early days of Ada 83 usage in space, there were quite a few codes of
practice that forbade the use of generics, tasking, access types and so
on. Anything "dynamic" seemed to be considered a bad thing.
My personal opinion is that this is ridiculous. It is possible to use
dynamicism and still be safe and reliable, it just requires more
discipline from the programmer and, in some cases, a clear understanding
of how a feature is implemented by your choice of compiler.
