Hello Internals!
The following RFC aims to make empty() have a variable arity:
https://wiki.php.net/rfc/variadic_empty. This is a simple feature that enables
for a short-hand notation of checking multiple expressions for emptiness (which
is a pretty common thing to do).
I have avoided including the is_*() functions into this RFC because my main
priority is to get this particular feature into PHP 7.0 before feature freeze.
Provided I have some free time over the next week, I'll write up another RFC +
patch to cover the is_*() functions.
Thanks,Tom
