Several major issues here:

* The exact syntax and semantics of `__traits(properties)` are 
not specified anywhere.
* The rewrite involving `@property` arguments and `inout` 
parameters is not adequately explained. Under what circumstances 
is this rewrite performed, and how *exactly* is the function 
rewritten?
* The array indexing examples have nothing to do with property 
access. Instead, they are a new form of operator overloading.
