Can we fix reverse operator overloading (opSub_r et. al.)?

Indeed, I even think that the concept of operator overloading is wrong.
In C++, operator overloading was just for syntax sugar. That's wrong: 
pretty much everything that you want overloaded operators for, is 
performance-critical. And that implies you need to deal on the level of 
complete expressions, not individual operations.

Despite that, I'd still like to see this patch (or something like it) 
especially in DMD1 so that we can have a _reasonable_ syntax ASAP.
