[Ironruby-core] Evil Fun with IronRuby

We wouldn't be very true to Ruby if we didn't allow you to "monkey patch" CLR classes and interfaces.  And really, this isn't all that different than using extension methods in C#.

All classes in IronRuby have a "RubyClass" object associated with them, even if the class is being imported from the CLR.  It's this object that defines and manages the Ruby aspects of the class implementation.

Hey all,

I posted the results of some recent experimenting with IronRuby to my blog at: http://faithfulgeek.org/2008/6/17/evil-fun-with-ironruby.  My question is, how do these things work under the covers?  Do .NET types that have a Ruby equivalent get treated as the Ruby type or is there an extra layer that allows any .NET type to be modified at runtime?  It's totally cool that any of this is possible, but I was very surprised that it is.

Thanks all!
