I like this syntax and expected behavior. The only problem is implementation. Anonymous functions those don't capture variables from lexical scope can be compiled once at file compile time, instead of evaluating in create_function(). But I don't see how it can be done with variable capturing. Thanks. Dmitry. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
