For me it's worrisome because future developers, that are just starting 
programming with PHP, will need more time to understand that a 
non-anonymous function, i.e. a function that has a name, may just as 
well benefit of a closure concept (except in the PHP language (if I 
don't count importing of global variables using the global statement)).

A closure is not a special kind of function, a closure is just a link 
between a function (named or unnamed) and the environment it has been 
defined in.

I totally agree with Keryx, we should use the correct names for these 
concepts. If it was up to me, I'd name the internal class used to 
represent lambdas Lambda.
