I guess that it could always use the integer representation of the resource=
.
Or, more sensibly, be converted to an opaque object that implements a __toS=
tring() method.

I have encountered some other issues in the engine exposed by this conversi=
on,
the biggest one being array_diff/array_intersect, so I could also spend som=
e time working on that extension.

Best regards,
