Hi all,

I think we can get rid of this error now when literal is returned.
The reason we have E_STRICT error is that legacy PHP didn't
support this, I suppose.

Is it possible to allow literal as referenced parameter for PHP7?
It's better to remove needless restrictions where it is possible.
HHVM seems already support this.

Any comments?
