No. I'm obsessed with finding out what closures are, since nobody seems to
have a good definition of them!

However, I have learnt some things: closures are something which functions
HAVE, not ARE. The func_closure attribute is just part of the
implementation of the closure. Some languages have closures and some
don't. And a closure is something that lets a function object access the
lexical scope that existed when the function object was created, e.g. the
namespace of the function which created it.

Am I getting there now?
