Subject: Re: [PHP-DEV] T_AS in closures
From: narf@devilix.net (Andrey Andreev)

From what I read (and that's all of it), people on the list were
against (expression) as $foo and wanted more usage examples in the
RFC. The overall reception seems positive to me. :)
The author withdrew it because they wanted to add more stuff to the
patch and then (apparently) never proposed it again.

Actually, that discussion also mentions use (...) with regular
functions, which would also be nice, but probably better left for
another thread.
