I'm curious about the status of Fast ZPP and it's usage.
The RFC says it reduces function call overheads by 90% and
I didn't see reason why we shouldn't move to Fast ZPP.

"For some really simple function like is_string() or ord() the overhead of
zend_parse_parameters() may be about 90%."
https://wiki.php.net/rfc/fast_zpp

I'll use it for functions called many times.

Regards,
