Can we throw an E_NOTICE when foreach targets a reference? (The other
there's many way to use reference, not only in foreach. don't do
reference unless u know it's really needed.
Sean's not so much referring to his own problem as (like you said) the
solution is a fairly simple matter of following strict coding practices.
He's trying to address the problem of unexperienced developers seeing this
behavior and (wrongly) reporting it as a bug, or worse, assuming PHP is just
"broken" and therefore shouldn't be used.
That said, I'm not convinved this needs a notice, but I'm certainly not
against it. Perhaps we should split the difference with an E_STRICT.
