`or` does not meet expectations?

[eevho]

🐛 The bug

exactly('18').or('19', '20'): (?:18|1920)
exactly('18').or('19').or('20'): (?:(?:18|19)|20)

I want to know if this is the design, but I understand that the variable argument of or is more reasonable if it should conform to the target expression?

🛠️ To reproduce

🌈 Expected behaviour

Target expression: (?:18 | 19 | 20)

That's a nice idea, I think supporting an array of args should be the second option.
