IMHO this is done by Perl converting HASH to ARRAY internally. In the same
way Perl converts array to scalar with scalar(@a), that is equal to number
of records in @a (equal to $#a-$[+1) and synonym of PHP's count($a).
With scalar(%a) you get number of used/allocated hash buckets, in Perl6
it would get a reference to %a (as stated in Exegesis 2).
IMHO all the perl complications should be passed over in first version of PHP
perl module.
In Polish there is a proverb "The Krakow (old Polish capital city)
has not been build at one". I.e. start from the simple extension
and .. extend it.

That is why PHP variable could be one from the two:
- a perl object
- a PHP variable independent from the Perl variable, mapped to scalar,
or array/hash array during the copying phase.

IMHO when object is destroyed on the PHP side, the Perl GC is used on the Perl side.

IMHO PHP is similar to Perl5, and I have heard of PHP/Perl module
a few years ago. It is just a matter of time ... the module need to exists.

+1000 for PHP for Parrot (AFAIK PHP it would run faster (?)).
