There are some cases where this could start becoming quite challenging and
we might get into reference counting/separation problems, i.e.:
function foo()
{
return array(1,2,3);
}
foo()[1] = 4;
or
function foo()
{
$arr = array();
$arr[1] =& $var;
}
foo()[1] = 2;
Anyway, these are the kind of things what we'd need to consider and with a
few more minutes I can start thinking of some rougher ones where we'd need
to return by reference and gracefully handle when you don't return by
reference...
I'm not opposed to this kind of syntax but it needs quite a lot of thorough
thinking and it's a great example of where test-driven development would
really be suitable (have like 20 of these weird cases in tests and try and
understand if we can get this 100% right).
