Hi,


I hardly worked on implementation of this patch for a week, but I still don=
't like it.

It makes 15% slowdown on each property update in existing PHP code (without=
 types), and I don't see a way to improve this.

Update of typed properties is going to be even more expensive.

Benchmark results are included into RFC (and not changed with the latest ve=
rsion of the patch).


-1.


Thanks. Dmitry.

Afternoon internals,

    The vote for typed properties has been restarted.

    Please take part: https://wiki.php.net/rfc/typed-properties

Cheers
Joe


To clarify though, didn't Wordpress and Mediawiki see only a 0.1%
slowdown? In my opinion that is definitely a tolerable performance hit
for such a feature.


I don't see any big value in this feature.
Most framework access object properties through getters and setters anyway.
They can be and should be used to provide type-safe API.
Another level of protection that makes slowdown instead of expected speedup=
, dosn't make any sense.


Thanks. Dmitry.
