Oh. Interesting. I had a chat with Robin Houston (author of Want) about this. Robin says that Want can't scan back past a tie, because the information it would need is in a local variable in a C function. (He was telling me this. I think he told me which function, but it wasn't all sinking in, as things have been a bit http://www.flickr.com/photos/twoshortplanks/28698637/ recently *) Would the core not being able to scan back past tie/overloading/magic/etc be a bug that needs addressing?

I was talking with Robin at the meeting on Thursday. ** to avoid distress I should clarify further that neither copenhagen.pm nor the state of the glass have anything to do with the aaaaaargh. Nor does any open source code. We know where the code in question lives, and its days are numbered. :-)
