How would I turn this ObjC into MacRuby?

[ MyClass conformsToProtocol:@protocol( MyProtocol ) ];

Currently this is not possible (same in RubyCocoa), but with the enclosed patch: $ ./miniruby -e "framework 'Foundation'; p 'foo'.conformsToProtocol(Protocol.protocolWithName('NSObject'))" true $ ./miniruby -e "framework 'Foundation'; p 'foo'.conformsToProtocol(Protocol.protocolWithName('NSDoesNotExist'))" false Any idea regarding a shortcut? (Protocol.protocolWithName is too long). For example we could automatically convert symbols to Protocol objects. Also, calling #inspect on a Protocol object currently crashes (because it's not NSObject-based, where inspect is defined).
