Hi Matt, As a user-land developer, I would be very much against changing this. I’m sure it’s probably not a particularly common way to format code, but the ability to chain method calls, starting from a static call and have it formatted with one method call per-line is quite useful IMO, eg: ``` MyModelClass ::find(1) ->where(‘foo’, time(), ‘>’) ->where(‘bar’, null, ‘is not’) ->readAll(); ``` But more generically - I can’t see why you’d think that this one particular instance of extra whitespace being insignificant is a problem, when extra whitespace is not significant anywhere? In other worse, can you explain why you think it’s a problem that whitespace is not significant in static method calls, but it’s not a problem everywhere else where it’s not significant? The two following examples are the extremes of extra whitespace vs minimal whitespace, and your suggestion would introduce an arbitrary inconsistency for one specific case. ``` <?php namespace Foo; class Bar implements \JsonSerializable { public function jsonSerialize(): mixed {return self::class;} public static function create(): static { return new static(); }} $f = Bar::create(); echo \json_encode($f); var_dump($f); ?> ``` ``` <?php namespace Foo ; class Bar implements \JsonSerializable { public function jsonSerialize ( ) : mixed { return self :: class ; } public static function create ( ) : static { return new static ( ) ; } } $f = Bar :: create ( ) ; echo \json_encode ( $f ) ; var_dump ( $f ) ; ?> ``` Cheers Stephen
