I actually tried this, but the problem seems to be that Protocol is not a true
class. So if I try to do anything with the protocol parameter from MacRuby, I
get an error:
*** NSInvocation: warning: object 0x7fff71192488 of class 'Protocol' does not
implement methodSignatureForSelector: -- trouble ahead
*** NSInvocation: warning: object 0x7fff71192488 of class 'Protocol' does not
implement doesNotRecognizeSelector: -- abort
Even just comparing it to another protocol object using protocol ==
Protocol.protocolWithName('...') leads to the same result.
Any ideas as to how this could be made to work?
