In order to access instance variables, one must use the $this-> prefix. The problem with this is that it reduces expressiveness in the language and increases the amount of unnecessary decoration, reducing readability.

I disagree with this premise. The $this here is not just decorative syntax, it's an actual variable, which can be passed around just like any other variable. The -> is then the standard way of accessing a property or method, applied to that variable. This is beautifully simple, and expresses what's going on perfectly: if you look at $this->foo, and ask "which foo is being referenced here?", the answer is clearly "the one which is a property of $this". The only places I can see value in a shorthand are in constructors and setters, where you're just copying from one name to another ($this->foo = $foo). But the part that's redundant there is the variable/property names, not the $this, so what you need is getter/setter support, or shorthand constructors (you should be able to find previous RFCs for both). Regards,

I concur. I don't see much advantage of a short hand in this case, but I would love to see someone pick up both the property RFC (which implied short-hand getter/setters) and shorthand constructors. (It's undoubtedly too late for 7.0, but they'd be great additions for 7.1.) --Larry Garfield
