There is no difference between a function and a variable which holds a
closure in many languages (e.q. JavaScript, LUA, ...), so you don't need
any extra syntax rules.
function foo() {
}
foo();
var bar = function() {
}
bar();
It's not possible to make the same unification with PHP's $, however I
don't see a way to remove $.
