@Marcello: actually, I am also of the idea that there's no real additional
value in such a syntax...
Since I'm using ZF2 (yeah, that framework that converts array to
applications) I am kinda used to have dozens of function () {} closures
for service factories: so far no problems with it.
As stated before, it spares 9 chars while the end developer (devops or
whoever coding instead of of the devops) loses a lot of readability that is
not really such a big problem.
Also, as it is for DSLs, you could always use a parser to handle this kind
of thing in your own domain.
What exactly is the limit that you see when applying the more verbose
function () {} syntax? I am just wondering since moving to {} will
still not make this portable to any platform except PHP itself.
