<moritz_> masak: why is that a bug?
<masak> moritz_: because it calls the Str method, but the attribute is undef.
<moritz_> masak: A.new ~~ Str, so I don't see why it should call
method Str at all
<masak> moritz_: well, it does.
<masak> so either way, it's a bug.
<masak> moritz_: actually, I'd argue that if you define your own .Str
method, and then call it, it should be called.
<masak> but it is, so that's no problem.
<moritz_> oh wait, you call it explicitly... yeah, sorry
<masak> np. it's a confusing bug.
<masak> the problem is that $.bar yields undef for some reason.
