Hmm. Could you share a use-case for this?

If you are accepting one or more of T then T has to be written twice without this.

Validator<Value> | Array<Validator<Value>>

((...args: any[]) => any) | Array<((...args: any[]) => any)>

vs:

OneOrMore<Validator<Value>>

OneOrMore<((...args: any[]) => any)>

The latter is DRY and is quicker to comprehend.

lodash uses their Many (same thing) abundantly.

I noticed lodash's uses ReadonlyArray which would probably be better.
