I mean, with numbers it's even more confusing (this might be a TS bug?):

    type SpecialNumber = number & { __brand: "SpecialNumber" };
    let n: SpecialNumber = 42 as SpecialNumber;
    
    n++;        // works (but should break)
    n+=1;       // breaks
    n = n + 1;  // breaks

I understand the purpose behind it, I just think it's needlessly confusing and obtuse, and would be curious to see any serious code base that uses branding.
