I wouldn't mention this at all. I'll state it again, loud and clear,
that references were *not* designed to enable you to create recursive
data structures, and they perform very badly for this purpose. The
leakage issue can be very serious - for instance, a leaking data
structure that leaks 30 bytes, can end up leaking megabytes if it's put
in a loop.
just stas ensured that I don´t have to worry about, no one puts
these in a looped structure, but I found it quite essential in
OO communication in PHP and speed-wise it performs good, better
then copying the required data into other objects and that´s not
the only reason to use these...
my current problems (only) with circ-refs:
a) circ-refs leak (a bit) doesn´t matter in most cases
b) var_dump() does not work with them
if there are more, please tell...
