It's interesting they haven't extended the language in the same way Fog Creek took VBScript/ASP, wrote a compiler for it and then started improving the language (a.k.a. Wasabi). I suppose PHP already implements practically every language feature you could think of (though the quality often divides the minds to put it lightly), so making it even bigger isn't going to make things better.<p>Or maybe they have and it's kind of got lost in the hype.
