#51083 [NEW]: Closures returned by functions/methods must be stored to be executed...

From: adam dot jorgensen dot za at gmail dot com Operating system: Linux PHP version: 5.3.1 PHP Bug Type: Feature/Change Request Bug description: Closures returned by functions/methods must be stored to be executed... Description: ------------ When returning an anonymous function from a method or function call, the returned closure is not directly executable in a logical fashion. The closure needs to be stored in order to be executed or must be called via the call_user_func family of functions. This is fairly illogical and inconsistent with the idea of closures. Reproduce code: --------------- function test($a) { return function($b) use($a) { echo $a . ':' . $b . '<br/>'; }; } call_user_func(test(1), 2); $x = test(1); $x(2); test(1)(2); Expected result: ---------------- Output should be: 1:2 1:2 1:2 Actual result: -------------- Execution fails.
