Subject: Re: [PHP-DEV] [RFC] Allow "use( $longname as $alias)" syntax for

That depends on the scope, it can be very big - e.g. global scope. But
more important is not that it is big by itself, but that it retains
variables that are otherwise to be freed and thus increases overall
memory usage.

If you know any way to do it, please tell. Please account for $$var, etc.

I don't think it's very complex syntax - you just specify the variables.
It takes 1 minute to read the manual and you know how to do it forever.
It's not the rocket science to write use($a, $b).

That's entirely different topic.
