Imagine a command like this

import ArgumentParser

struct Absolute: ParsableCommand {
    
    @Argument() var number: Int
    
    func run() throws {
        print(abs(number))
    }
}

Absolute.main()

you can run

command 5

and it works. but running

command -5

fails with Error: Missing expected argument '<number>' which makes sense.

I would have expected being able to pass the argument as "-5" but that doesn't work either.

Any advice on how to handle this?
