I wonder where these coercion rules are described. The manual has a
section about "Converting to array"[1] which actually describes casting,
and is obviously not what is happening when the subscript operator (as
the langspec calls it[2]) is applied to non-null scalars.
There's a manual page on "Type Juggling" which is probably more
relevant: http://php.net/manual/en/language.types.type-juggling.php
Interestingly, it notes that:
> The behaviour of an automatic conversion to array is currently undefined.
So, at least as far as that reference point is concerned, any change in
behaviour could be justified (if agreed by RFC) as defining what was
previously undefined.
