State-Changed-Why:
Structure tags give the desired functionality.
The problem with your idea is that the compiler doesn't know
what a treenode is until it has parsed the whole lot. In particular, it doesn't know it's a type, or if it was
a mis-typed "unsigned" etc. This makes the
parser far more complicated than it currently is,
would introduce some bizarre messages I'm sure, and for
little (IMO) gain.
