The main reason of this topic was to figure out requirements for C++11
attribute parsing, but some of the things we discussed (attribute subject
checks, common argument checks) are applicable to handling all kinds of
attributes. So, wherever it is possible to make code work for all attribute
styles for free, I think, we'll try to do so.
