Why is Boolean not true and false?

[jaulz]

First of all, thanks for this cool library! However, I wonder why you used 1 and 0 for Boolean instead of true and false? Something like this causes an issue right now because the return parameter is not a real boolean:

TPartial extends boolean = Contains<TParams, typeof Wildcard>

Did I miss anything?

Hi!
I guess because with Boolean you can't do something like that

export type Select<U extends any, M extends any, match extends Match = 'default'> =
    U extends unknown
    ? {1: U & M, 0: never}[Is<U, M, match>] // HERE IS THE DEAL
    : never
