The extension method Where() should be matched

I use the most recent Mono.CSharp downloaded today 16th of December 2011 from Github.

See the 2 screenshots attached.
In the left one the extension method Where<T>(this IEnumerable<T> ) should be matched by GetCompletions().
The right screenshot proves that the evaluator context knows the method Where(), since it recognizes that i is an integer.

On a side note, could it be possible to get a GetCompletions() method that would returns something more precises than just strings, like members or types metadatatokens + their parent assemblies for example?

Btw, congrat for this awesome piece of code :)

The source code:

using System;
using Mono.CSharp;
namespace ConsoleApplication1 {
   class Program {
      static void Main(string[] args) {
         var report = new Report(new ConsoleReportPrinter());
         var cmd = new CommandLineParser(report);

         var settings = cmd.ParseArguments(args);
         if (settings == null || report.Errors > 0) { Environment.Exit(1); }

         var evaluator = new Evaluator(settings, report);

         evaluator.Run("using System.Linq;");
         evaluator.Run("using System.Collections.Generic;");
         evaluator.Run("IEnumerable<int> Ints;");
         string prefix;
         var propositions = evaluator.GetCompletions(@"Ints.Whe", out prefix);
