  DLR:
  Fixes bugs in type inference:

    1) By-ref generic parameter
    public void Foo<T>(ref T x);

    Foo(1)
    Foo(StrongBox())

    2) Multiple generic parameters
    public IEnumerable<TResult> Select<TSource, 
TResult>(IEnumerable<TSource> source, Func<TSource, TResult> selector);

    3) Generic arrays
    public int Foo<T>(T[] x);

    4) Type shape difference
    public static int f5<T>(Dictionary<Dictionary<string, T>, 
Dictionary<int, T>> arg);
    C.f5( Dictionary[List[str], Dictionary[int, str]]() )

    In general type inference seems to need more test coverage - various 
type shapes, arrays, ref/out with and w/o strong boxes, params array, 
params dict, optional, named combinations.
    I've added a few tests for the cases above to Ruby unit tests.

  Ruby:
  Implements IInferableInvokable on blocks so that they can be coerced 
to Func<object*> and Action<object*> delegates:
  Enumerable.select([1,2,3], lambda { |x| x + 1 }).each { |a| puts a }
