    Parameters:
      `ordinal` - the position with the parameters to insert to. This ordinal must factor in the presence of auto-parameters which may be injected dynamically based upon calling convention and return data type. Parameters may not be inserted befor an auto-parameter.
      `var` - the variable to add as a new parameter.
      `source` - the source of this parameter which will be applied to the parameter symbol and overall function signature source. If parameter has a null or default name a SourceType of DEFAULT will be applied to the parameter symbol.
    Returns:
      the Parameter object created.
