You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.

Several of these are explored in the next chapters of the tutorial.

## Order matters { #order-matters }

When creating *path operations*, you can find situations where you have a fixed path.

Like `/users/me`, let's say that it's to get data about the current user.

        assertFalse(auth.matches("ftp://hostname:111/"));
        assertFalse(auth.matches("ftp://hostname:xx/"));
        assertFalse(auth.matches("ftp://hoge/test/aaa.html"));
        assertFalse(auth.matches("ftp://hoge/test"));
        assertFalse(auth.matches("ftp://hoge/"));
        assertFalse(auth.matches("ftp://hoge"));
        assertFalse(auth.matches("ftp://"));
        assertFalse(auth.matches("http://hostname/"));

    // Break apart the domain into UTF-8 labels, i.e. foo.bar.com turns into [foo, bar, com].
    val domainLabelsUtf8Bytes = Array(domainLabels.size) { i -> domainLabels[i].encodeUtf8() }

    // Start by looking for exact matches. We start at the leftmost label. For example, foo.bar.com
    // will look like: [foo, bar, com], [bar, com], [com]. The longest matching rule wins.
    var exactMatch: String? = null
    for (i in domainLabelsUtf8Bytes.indices) {
