Well, simple logic could leads to scenarios that aren't that easily
understandable. My original question arose out of this function I'm
writing, which returns a large array of arrays. Knowing that PHP's
copy-on-write mechanism creates copies when "references" are returned,
I didn't want to return a whole array-ful of them. The line $lines[] =&
$line did look like that's what being created.
