Missing inout gets C# error message rather than Cobra error message.

[torial]

If a call to a fxn that has inout parameters is made w/o the inout parameter, the C# equivalent message is given: "error: Argument "1" must be passed with the "ref" keyword" However, adding "ref" before argument 1 does not fix the issue, adding "inout" does.

%% args -ref:System.Xml -ref:System.Drawing

use System.Windows.Forms #from "System.Windows.Forms"
use System.Xml #from "System.Xml"
use System.Text.RegularExpressions
use System.Drawing

        .text = 'TMX Word Match Finder'

        .height = 600
        
        list = List<of int>()
        .getList(list) #error: Argument "1" must be passed with the "ref" keyword
        .getList(inout list) #this compiles fine if above line is commented out.
