#48742 [NEW]: closure vs anonymous functions.

From: teftin at gmail dot com Operating system: PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: closure vs anonymous functions. Description: ------------ documentation states for function.anonymous states: "Anonymous functions, also known as closures ..." this sentence might be true in context of (current) php implementation, but it is not true in general, as not all anonymous functions are closures, and closures don't have to be connected to anonymous functions or functions at all. http://en.wikipedia.org/wiki/Closure_%28computer_science%29 ... The term closure is often mistakenly used to mean anonymous function. This is probably because most languages implementing anonymous functions allow them to form closures and programmers are usually introduced to both concepts at the same time. These are, however, distinct concepts.
