I personally don't see much advantage in making PHP code less readable
and harder to parse. Also, "automatically use () all of the (compiled)
variables" does not look like a good idea - first, users have no idea
what compiled variables are, so the result would be unpredictable for
them, second, if there are a lot of variables in the scope (like global
scope) it would have huge performance costs for no gain.
Also, this syntax does not allow "use by-ref" which the existing syntax
does allow.
I think we already have syntax for anonymous functions and it works. The
only addition in this RFC is automatically gobbling up all local
variables, which in vast majority of use cases is not what the function
needs.
