I also like the functionality.

Rather than munge existing syntaxes, an altogether new one would be more clear:

   self->name = self.metadata->name

I like the arrow syntax because is the lookup process can be more involved
than a simple dictionary lookup (perhaps traveling up to base classes).
IOW, getattr(a,n) is not always the same as a.__dict__[n].
The a.__getattribute__(n) process can be more complex than that
and a bracketed dictionary-like syntax would misleadingly mask the lookup 
process.
