I'm usually a lurker on here, but thought I'd through in my 2p on this one...Delphi (Object Pascal) has a similar feature, that I've had some experience of using, and I never liked it. Why? Because it only leads to confusion, mainly because the separation of object and method leaves you unsure of what is actually being called. Consider the following: function do() { echo "hello"; } $class=new class; with($class) { do_something(); do_more(); do(); } Now, within my with(), am I calling the class method do() or the function do()? Not clear at first glance.
It may not be clear to some people, but there are many things in the every language that aren't necessarily obvious and I don't think that's a reason not to implement something.
To me this is actually quite clear. When you use with() you are defining a temporary local scope, so your call to do() would first check if the with() object contains that method, and then check the global scope if not.
And the whole thing gets even more complex if you can start nesting with() constructs.
Again this seems simple to me, you just need a stack of with() objects which are walked up to resolve any references.
I suspect this wouldn't be trivial to implement, and for me it doesn't add any value - only potential confusion.
I see great value in this - it makes for cleaner looking code. I need more than 10 fingers and 10 toes to count how many source files I have that contain long sections where each line contains multiple references to the same object.
