I don't think this helps, because you can put brackets around any expression, for precedence, and any expression can appear on the left of an array literal: $foo = [ ($bar + 1) * 2 => $baz ]; So the following, while redundant, is currently valid: $foo = [ ($bar) => $baz ]; Regards, -- Rowan Collins [IMSoP] -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
