This bug pretty much rules out backwards compatibility with most php4
OOP programs. It's quite silly to say that returning a reference by
calling another function that returns a reference is "bad" programing
practice. And by the way, C++ has no problem with returning pointers.
Just to be clear:
function &getHomeTeam()
{
return $this->getTeam(TEAM_TYPE_HOME);
}
Really should work.

Fatal error: Only variables or references can be returned by reference

I agree with Zeev on this one, this shouldn't be fixed. People will
need to learn to write good code one day or the other, and returning a
reference like that is VERY bad practice (try to do that in C++!). Even
returning a reference to a local variable like this example should
produce an error :
class foo
{
function &bar()
{
$whatever = 5;
return $whatever;
}
}
because $whatever should not exist anymore after function bar return
(according to correct scope rules), thus this reference is not
referencing anything anymore... Instead of always asking to fix bad
programming practice people should learn the correct way to do it. This
is my opinion.

Any idea yet if this will be fixed/addressed or should we start
converting scripts to not use referenced return type or build variables
that get returned?

Yes, it is quite complicated. You can only return variables by
reference, a function's return value is not something we can 'connect'
to...
