I like it! regarding $foo->bar()()… is it possible to use precedence rules here? something like: ($foo->bar())(); > What do you think? If somebody has better idea btw - maybe make something like {foo()}() - and > make that work for any expression inside {} - that might work too. So, what do you think? why curly braces? Parentheses would feel more natural here. Would be nice if something like this worked too: (new Class())->method();
