Well, you cannot do "$a = 'phpinfo'; $a();" as well, so it's consistent with that. I think what you refer to would only make sense if that were allowed. You can. This is valid. OK, I know where I got this idea. "$a = 'phpinfo'; $a();" is actually the only valid case. array callbacks or 'Foo::bar' are forbidden. In order to be called as instance methods, the closure properties needs to have a bound instance -- preferably -- very preferably -- the instance where the closure is stored. In this case, it doesn't make sense to allow 'function' to be called, because then we wouldn't have anything with which to fill the $this pointer. I guess it could make some sense for static calls, though. -- Gustavo Lopes
