 Helper function that populates the argument list given that user may need to use a mix of
 named and unnamed parameters. This is relevant because named parameters are not
 identical to unnamed parameters due to string trimming, and when dealing with strings
 we sometimes want to either preserve or remove that whitespace depending on the application.
