[Ironruby-core] Range#=== operator

Would it be fair to follow this as a general rule: when coding Ruby methods
in C#, if you are calling code that is exposed as a method or operator in a
Ruby class or module then invoke it via a DynamicSite, if it is purely
private code to the C# method then call it directly?

Exactly. The trick with library methods is to figure out what pattern MRI
uses. Typically, they do a method lookup on the type, which in our world
translates into a DynamicSite. However there are some places where they just
call some library method directly and bypass any overridden/monkeypatched
method. So it requires some experimentation :).
