## Incluir o mesmo roteador várias vezes com `prefixos` diferentes

Você também pode usar `.include_router()` várias vezes com o *mesmo* roteador usando prefixos diferentes.

Isso pode ser útil, por exemplo, para expor a mesma API sob prefixos diferentes, por exemplo, `/api/v1` e `/api/latest`.

    @Test
    @DisplayName("equals: this shorter but same prefix -> true (observed behavior)")

        // Arrange: left shorter than right but with identical prefix
        SecurityBlob shorter = new SecurityBlob(new byte[] { 1, 2 });
        SecurityBlob longer = new SecurityBlob(new byte[] { 1, 2, 9 });

		authFields := strings.Split(strings.TrimSpace(v4Auth), ",")
		if len(authFields) != 3 {
