Trying to fix the problems with callables would be a huge amount of work, and not actually give that much benefit. Even just documenting the problems with callables* is a non-trivial amount of work, and I suspect there are many horrors lurking with the SPL code related to them. > I believe we should look into... I'm pretty sure that choosing a different problem to solve that: * would be easier to solve. * provide more benefit in the long term. * not require breaking a lot of userland + internal code immediately, but instead allow for migration over a longer period. My thoughts on adding 'function types' are here: https://github.com/Danack/FunctionTypes/blob/master/function_type_rfc.md There's still more than a couple of known problems that need to be worked through, as well as probably unknown problems lurking. As email is not a good format for carrying out discussions, if people want to take part in that discussion, doing it in that repo would be better imo. Assuming the problems remaining can be addressed, that would give us a more useful feature, and the existing 'callables' can be slowly deprecated and maybe removed from PHP in the distant future. cheers Dan Ack *[problems with callables] - https://wiki.php.net/rfc/consistent_callables -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
