Subject: Re: [PHP-DEV] Return value of convert_to_*()
From: helly@php.net (Marcus Boerger)

Hello Andrei,

  we had a long decision about this issue already and decided that the
only reason for "Object..." in 5.0 and 5.1 was the lack of ability to
fix __toString() prior to 5.2. The current 5.2/6.0 behavior is what we
wanted in the first place and hence correct, or do we need to restart
the discussion again? Or am I again missing something here?

best regards
marcus
