    Try to get it so can not pass in -dyn and just use "red"
    Help says -dyn is optional, but can't get it to take it w/o
    e.g.
    noNameDynamicParam red # sets staticParam to red, prompts for dyn
    noNameDynamicParam -dyn red # ok
 
    Setting explicit postion and CmdletBinding(PositionalBinding) doesn't help
    DefaultParameterSetName="dyn" didn't help
    PositionalBinding=$false and removing position worked, but have to supply -static for second
