I'm sure it will let you make that label, but it won't be able to make any sense of it. Maybe I was slightly wrong that only syntax highlighting will be helped by the "standard" syntax, but the point remains that none of the (existing) tooling can properly make sense of those parts of the code. That $ isn't really a label, it's a reaction, which your linter knows nothing about and can't help you with; at best it can "work around" it.
