There's not really much win. In most cases the generated code is exactly the same.*) Such changes are nice to spot bugs as the compiler has more knowledge of the intention and to make C++ compilers happy when using these APIs as C++ is stricter on const. johannes *) there are few cases where this helps with inlining or passing params via register, but here we mostly deal with exported APIs which have to follow the platforms ABI rules. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
