Hi Stas,

It might be better to change RFC title.
My goal is sort out PHP behaviors which may seem strange.

If it's a bug, fix it. if not, document it so that users understand
what it suppose to do.

I agree. It's the way PHP works.

It might be better to document these, since there are many languages out
there and people have different expectations.

I've updated to
"Null string is handled as array" when string is accessed as array of char.
I appreciate better explanation :)
