If you opt for this solution, an enum is slightly more verbose but much 
clearer:

enum IsMessage
{
    Yes,
    No
}

this (int[] data, string text, IsMessage isMessage = IsMessage.No) {...}


auto s = new S(data, text, IsMessage.Yes);

vs

auto s = new S(data, text, true);


I would still prefer a factory method or a struct wrapper though.
