I gotcha. So in your example System.Core.rb was monkey-patching
Enumerable. You weren't actually resolving those method calls to the
extension methods in the System.Linq.Enumerable class.

I agree. In C# you add the namespace and those extension methods are only
available in that source file. So you have to add the namespace to each
file you want to use the extension methods. But in Ruby once they are added
to the object they are available everywhere. So I wonder what a Ruby-ish
solution would be. Does anyone on the list have any suggestions how
enabling extension methods could/should look?
