[feature] Support for out parameters

See original GitHub issue

Hello, I need to call IDictionary.TryGetValue method in my expression, as I understand out parameters are not supported now. I’ve tried to execute following code in TryWindow application:

var dictionary = new Dictionary<string, object>();
dictionary.Add("x", 5);
object number = null;
if (dictionary.TryGetValue("x", out number))
	return number;
return 0;

and have got following message:

Variable [out] unknown in expression : [out number]

Mb I did something wrong? Are there any plans to support out parameters feature?

I published version that add support for out, ref, in keywords and for calling methods with params parameter.

The implementation is a bit more permissive than in pure C# and also required to modify a bit the way the library search the right override of a method and how it manage parameters to call it. I made a few tests to ensure that the most cases work but if you find some bugs related to this don’t hesitate to open new issues.

Thanks guys I am glad that this will allow a bunch of new stuff with EE.
