Are you able to post any code that you've already attempted this with? Is there a specific error that's blocking you?

Does using the --dev-debug flag output anything more useful?

If you plan on having different typed parameters then you could also make an overloaded method which accepts the types of params you want to "do something" to, and call the respective overloaded method once for each param.

Any reason you can't pass in a list of strings for processing in this manner?
