Syntax to enter commands regardless of order

[sidbav]

Is there a syntax to specify a valid command regardless of the order the command is entered?

For example, I want the following commands to be valid:

cli> aa bb cc dd
cli> aa bb dd cc
cli> aa cc bb dd
cli> aa cc dd bb
cli> aa dd cc bb
cli> aa dd bb cc

Right now I believe you would have to explicitly state each command in the syntax like so:

aa { 
  bb { 
    cc dd;
    dd cc;
  }
  cc { 
    bb dd;
    dd bb;
  }
  dd { 
    bb cc;
    cc bb;
  }
}

It is fine implementing this when there are only a few commands which you want like this. (i.e here we have 3 keyword, so only 3! (6) to consider)

However, if you have lots of commands like this. then the amount of permutations that you need to consider grows quickly!

Any solution to this?

See #22 (and #23).
This is a sufficiently common request so I will try to look into it.

New "sets" feature added, see:
ed1997a

Example: aa @{ bb; cc; dd; }
