Yes.  Top posting means putting your reply above what people have sent p=
reviously.  On many mailing lists, including this one, that is discourag=
ed as it makes the thread harder to follow.  Instead, put your responses=
 inline between parts of what you're replying to, or at the very end.  T=
hen remove any parts of the previous messages not relevant to what you'r=
e responding to.

As Rowan notes, how it does work currently is critical, because we need =
to avoid breaking existing code.  Adding functionality is fine and good,=
 but breaking people's code is not, outside of some very controlled edge=
 cases.

Object destructuring would be better done using pattern matching.  Work =
is already in progress on that, though it's not yet ready: https://wiki.=
php.net/rfc/pattern-matching

I get the sense that's much closer to what you are looking for.
