In order to access instance variables, one must use the `$this->`

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.)
