Hi!

No, of course it won't - if we ever introduce indexing objects (which
probably will require rewrite of the HashTable, any takers?) it would be
very easy to index any object that does not implement __hash without any
BC problem, and convert all those implementing __hash to "return $this"
if desired.

There's no implicit conversion, and explicit one is a) inacessible in
userspace for anything but string and b) annoying for the same reasons
for which __toString exists.
