Unless I'm mistaken, this hasn't changed.  That meaning is just invoked using a
different syntax, with a type between 'auto' and the variable's name.

Indeed, I don't know whether Walter just forgot to remove it from the compiler,
planned to do it later or what.  But it ought to be at least deprecated now. 
This meaning of 'scope' was introduced in 0.174 back in 2006.
