    # When an exception is raised, in some cases `#inspect` is called on a huge
    # object graph to generate the message `"undefined method '...' for
    # <Dota::API::Match:0x...>"`. This can take several seconds, since
    # `Object#inspect` descends recursively into each instance variable.
    #
    # This mixin defines an alternative default implementation for `#inspect`,
    # which should be significantly faster than the default Ruby implementation
    # since it does not descend into the object.
