The C language forces the UNIX style of command arguments onto different 
systems, and in doing so, has achieved a certain level of portability.

Why can't the Ada language do the same thing (or even follow C's lead
and also specify the UNIX conventions)?  [In fact, POSIX/Ada provides this.]

Aren't all future operating systems UNIX based, anyway :-) ?
