    That's what regular expressions are for, no? What abuse?

    I don't understand what you're trying to achieve. Are you trying to
    hide the fact that you're using boost::regex from the interface, so
    that you can do this?

    some_type anyofaababc(/* what should be here? */);
    assert(anyofaababc == "aaa");
    assert(anyofaababc == "aba");
    assert(anyofaababc == "aac");
    assert(anyofaababc == "abc");

    If so, what are you envisioning to construct those objects with
    if not regular expression literals?  You'll end up using
    regex_match() in operator==() anyway, so again, what's the question
    exactly?
