Subject: [PHP-DEV] Should the engine be able to pass variables by reference of
 userland functions

Hello internals,

While working on cleaning up the FCI/FCC API I stumbled upon the
zend_fcall_info_args_ex()
function.
This function allows the engine to pass "variables" to userland functions
that expect a by-ref parameter.
This is currently only used within php-src in PDO when calling the
constructor of classes where the result of a statement should be stored in
PDO::FETCH_CLASS mode.

I am wondering if this makes any sense to continue support in general, and
thus in this specific case. As every other engine call to userland function
passes by value.

A PR of this change is located:
https://github.com/php/php-src/pull/9725/files

What are your opinions?

Best regards,

George P. Banyard
