Being able to pass options after operands

Created by: sagikazarmark

I am not sure which is the POSIX standard:

command operand --help: --help parsed as option

It would be good if the above example could work.

It is not that hard to implement it, however the CommandLineParser must loop through all the provided options. I can send a PR for it.

But I would like to know whether not supporting this is a decision made or just implemented this way.
