Subject: RE: [PHP-DEV] Operator overloading for userspace objects
From: jan.h.boehmer@gmx.de

> Unfortunately, this implementation goes in the wrong direction: PHP =
already has full internal support for operator overloading through the =
do_operation object handler. Operator overloading should be exposed to  =
userland through that handler as well.

I have made another implementation =
(https://github.com/jbtronics/php-src/tree/operator_overloading) which =
provides an standard handler for do_operation, which calls the functions =
in user space.

I also removed the __compare magic function from my implementation, so =
this can be handled separately.

Another thing: What are your opinions on overload the bitwise not =
operator (~)? My implementations offers every other bitwise operator and =
this one would complete the set of bitwise operators. On the other hand =
unary operators does not have much use for objects and maybe encourage =
people using them as "shortcut" for calling things on the object, where =
an explicit method call would make the intend function more clear.
