I am OK with renaming them using OP_ADA_ as a prefix, but I would
go the other way.  Instead of having language-specific operators,
make them available to everyone with standard, well documented,
semantics. Many of them might be only used in Ada at the moment,
but I think that's OK and there is no reason that some operators
such as "UNOP_IN_RANGE" for instance might not be used by other
languages.
