Well, I'd like to actually see it in any other language. The obstacles
seem to be:
- Ignorance (DBC is quite new, I've been aware of it since just 5
years...)
- No conventions how and where the assertions should be written
- No binary formats that retain the assertions (this goes from object
formats to CORBA)
- It is serious work to write a "flat-short" tool that scans the
inheritance hierarchy and extracts all contracts

Regards,
Joachim
