I don't know if this was considered a non-issue when I last raised it, but in this synopsis:
http://dev.perl.org/perl6/doc/design/syn/S12.html I see that the behavior of .can() metamethod hasn't been updated. My concern is that someone calls $object.can('bark') and they expect to pass an integer to the method but there is no method 'bark' which accepts an argument. .can() will still dutifully return a method (or methods) to you. Thus, .can() will lie to you because you can't say: $object.HOW.can( ... some signature ... ) Perl 5 couldn't really solve this and programmers just had to "know" that all methods were implicitly variadic. I seem to recall that Larry had an idea about how to specify a signature (I could be misremembering and I can't find the response). Has there been any more thought about how to appropriately deal with this? Though I could be in the minority, this does seem like a glaring hole in Perl 6's OO behavior.
