I would love to see this come to PHP. I also do a lot of Python development and I really like its operators module, which provides function equivalents to the intrinsic Python operators. Have a look: https://docs.python.org/3/library/operator.html Although the any() and all() functions are my favorites, having the full range of operator functions would be great. That could ultimately yield a proper counterpart to the range of array_* functions which support any iterable in stead of just arrays. Think of a keys() function that is a generalization of array_keys(). This reminds me of the iter library that Nikita created: https://github.com/nikic/iter So yes, this can also be done in user space. Having it built into the language has advantages though: * High adoption rates, making lots of existing PHP code more concise * Possibly better performance Regarding performance: Since we already have opcodes for handling operators, it may be possible to extend these to consume arbitrary numbers of operands from iterables. Then, an operator function like any() would compile into its equivalent operator opcode. Finally, that opcode can probably be JIT compiled into a tight loop in machine code. So a +1 from me for adding any() and all() but let us also consider the general problem of lacking iterable support in PHP. Perhaps that could be the subject of a followup RFC.
