    @summary
      Validate that all values passed are valid IPv6 addresses.
      Fail compilation if any value fails this check.

    @return
      passes when the given values are valid IPv6 addresses or raise an error when they are not and fails compilation

    @example **Usage**
      The following values will pass:

        $my_ip = "3ffe:505:2"
        validate_ipv6_address(1)
        validate_ipv6_address($my_ip)
        validate_bool("fe80::baf6:b1ff:fe19:7507", $my_ip)

      The following values will fail, causing compilation to abort:

        $some_array = [ true, false, "garbage string", "1.2.3.4" ]
        validate_ipv6_address($some_array)
