> One thing I used to hate about PHP but then kinda grew to like was variables being prefixed with a $, as it makes it real easy to distinguish between functions and variables at a glance. This is great for a lot of code but it's probably my biggest complaint about the language these days. PHP supports first-class functions, which is great until you realize all your functions stored in variables have $ at the front. So now, not only can't you use $ to distinguish variables from functions (because sometimes they're both) but you have to remember if something is a Closure* or not. * another minor pet peeve is that you have to explicitly tell a function what variables it can see from the surrounding scope, but all anonymous functions inherit from a class called Closure whether they can see anything outside their own scope (a closure) or not.
