Playing around, I see that this works



include System

Generic = System::Collections::Generic

Linq = System::Linq



# var list = new List<Int32>();

list = Generic::List[Int32].new

list.add 1

list.add 2



# list.Average();

puts Linq::Enumerable.average(list) # it knows it''s a list of int32

=> 1.5


This is incredibly cool by the way, however, I can''t work out how to
pass types to a method which needs them, such as Linq''s
IEnumerable.Cast.
This was my best guess, and it fails



# list.Cast<Double>();

Linq::Enumerable.cast[Double](list)



I also tried



Linq::Enumerable.cast(Double, list)

Linq::Enumerable.cast(list, Double)

Linq::Enumerable.cast[Double](list)

Linq::Enumerable.cast(list)[Double]
Is this actually implemented, if so how can I use do it?
