Description

In the php 8 there is a new mechanism, which is attributes. However, in editor, they look like comments. E.g.

#[Attr(...), Attr(...)]
private int $a;

In single lines it can be skipped, but attributes can be multilines, what makes it totally wrongly colored. E.g.

#[ArrayShape([
	'id' => 'int',
	'month' => 'int',
	'day' => 'int',
	'usual' => 'int'
])]
