One solution would be to just accept any parameters in any order and then check for duplicates in a second step. If you want to include the position of duplicate arguments in the error
message, you could parse the argument together with its position (`tuple2 getPosition arg`)
An alternative would be to use the parser state to keep a record of the parsed arguments and then produce an error as soon as you get a duplicate, but that would be slightly more complicated.

Hello,
I'm having trouble wrapping my brain around an elegant solution to parse flag parameters in an arbitrary order. For example, allowing the user to interchange something like this:
myCommand -IsA -IsB
with this:
myCommand -IsB -IsA
Can anyone help?
