I just don't see any solution to make unknown options work without either -- requiring --something=10 format -- requiring that all positional options are at the end

What about the combination of (if some user-settable switch is thrown, but not by default):

* allowing unknown options -- these are considered positional parameters * rearranging the argument list such that all positional parameters are moved to the end

This way:

program --unknown 42 --known-flag --known-arg value

is handled as if it were (in standard UNIX command-line-ese):

program --known-flag --known-arg value -- --unknown 42

Looks possible. I'll add this suggestion to my todo. - Volodya
