Path objects also override the / operator to join paths

This is both cool and gross... gives me C++ vibes (operator overloading abuse).

    Scapy is another library where they redefined / to layer packets, such that you can write:

    IP(dst="172.23.34.45") / UDP() / DNS(…)

    Then Scapy has magic so that on serialisation, the UDP layer knows defaults to dport=53 if the upper layer is DNS, and it can access the lower layer to compute its checksum.

    And don't forget that strings have a custom % (as in modulo) operator for formatting:

    "Hello %s" %(username)

    Of course in modern Python, f-strings will almost always be more convenient

    They could have chosen a better operator. But the functionality is fantastic. Makes working with paths so much easier. And you can even use slashes on windows paths.
