I am all for consistency, but if I look at this: >Example of expressions those meaning changes: > // old meaning // new meaning > $$foo['bar']['baz'] ${$foo['bar']['baz']} > ($$foo)['bar']['baz'] > Foo::$bar['baz']() Foo::{$bar['baz']}() (Foo::$bar)['baz']() > $foo->$bar['baz']() $foo->{$bar['baz']}() > ($foo->$bar)['baz']() Those last 2 lines (old meaning) are exactly as I would have read them without thinking. So.. either I just got used to some kind of subliminal rule over all these years or I'm missing something. They're not variable variables, either. Somewhere in the proposal you write "It follows normal left-to-right semantic". This sounds very good in theory, but right now it feels a little unintuitive. Greetings, Florian
