[Dbix-class] many-to-many with attributes (again)

Great and not so great. This means that whenever I add attributes (be it new
columns or just new custom methods) to the proxied class I'll have to
update the proxy array with these attributes, right? This is quite error
prone IMHO. I need full access to _all_ methods through the proxy.
Is there any way around this?

Yeah, maybe nobody has a clue how to accomplish a more elegant solution in a
sane way :) Maybe you can point us in the right direction ...

Also, due to the fact that the DBIC wiki is offline for quite some time now,
there's no documentation anywhere concerning this method of accessing
attributes in a many-to-many link-table. Shouldn't this be in the Cookbook
or somewhere else? If so, I could provide a doc patch for it because I was
lucky enough to save the wiki page before it went off :)
