Using use in PHP
A rather obscure quirk of PHP is the use keyword - not for namespace importing, but as a way to selectively import variables from the defining location into anonymous functions. If that doesn't mean much to you, check out this post. Go on, I'll wait.
Good, now that you got that, I would like to continue with a little note of my own: basically, it's (also) a way to curry in variables that you don't want to have to specify when calling the function, but still want available, much like currying in Javascript et al.
Just my 2¢...
