A selector cannot be nil

[vincent.isambart@…]

In Objectve-C a selector can be nil, for example the following code is correct:

NSMenuItem *dummyItem = [[NSMenuItem alloc] initWithTitle:@"" action:nil keyEquivalent:@""];

but in MacRuby we get an error:

% macruby -e "framework 'Cocoa'; NSMenuItem.alloc.initWithTitle('', action:nil, keyEquivalent:'')"
-e:1:in `initWithTitle:action:keyEquivalent:': can't convert Ruby object `nil' to Objective-C value of type `:' (ArgumentError)
     from -e:1:in `<main>'

So I think MacRuby should support conversion from nil for selectors.
