May be namespace states your complaints. It doesn't add a whole new syntax, only kinda one extra level of indirection, naturally reusing existing feature of operator overloading, and I think it should look natural to compiler too: it's the same as operator overloading, compiler already does it.

And calling properties is only one aspect of the problem. The other is declaration. You heard it: implicit backing storage, default trivial implementation, type consistency. We don't have problems with calling properties. In fact complaints about current design originates from problems with property declaration: the problem is compiler doesn't know what is a function and what is a property.
