    Each of the provided `paths` is tested and the first producing a valid result will be returned.
 |

    The next path will also be tested if the path branched but no results could be found.
 | 
						||
    Supported values for traversal are `Mapping`, `Sequence` and `re.Match`.
 | 
						||
    Unhelpful values (`{}`, `None`) are treated as the absence of a value and discarded.
 |

    The paths will be wrapped in `variadic`, so that `'key'` is conveniently the same as `('key', )`.

        - `None`:           Return the current object.

                            like `{type}`/`{func}`. If a `type`, returns only values

                            of this type. If a function, returns `func(obj)`.
 | 
						||
        - `str`/`int`:      Return `obj[key]`. For `re.Match`, return `obj.group(key)`.
 | 
						||
        - `slice`:          Branch out and return all values in `obj[key]`.
 | 
						||
        - `Ellipsis`:       Branch out and return a list of all values.
 |

        - `tuple`/`list`:   Branch out and return a list of all matching values.

                            Read as: `[traverse_obj(obj, branch) for branch in branches]`.

 | 
						||
                            Read as: `[value for key, value in obj if function(key, value)]`.
 | 
						||
                            For `Sequence`s, `key` is the index of the value.
 |

                            For `re.Match`es, `key` is the group number (0 = full match)

 |

                            Read as: `{key: traverse_obj(obj, path) for key, path in dct.items()}`.

 |

        `tuple`, `list`, and `dict` all support nested paths and branches.

    @params paths           Paths which to traverse by.
 |

    @param default          Value to return if the paths do not match.
 | 
						||
                            If the last key in the path is a `dict`, it will apply to each value inside
 | 
						||
                            the dict instead, depth first. Try to avoid if using nested `dict` keys.
 | 
						||
    @param expected_type    If a `type`, only accept final values of this type.
 | 
						||
                            If any other callable, try to call the function on each result.
 |

                            If the last key in the path is a `dict`, it will apply to each value inside
 |

                            the dict instead, recursively. This does respect branching paths.

    @param get_all          If `False`, return the first matching result, otherwise all matching ones.

                            If `True` strings get converted to `int`/`slice` if needed.
 |

    @param traverse_string  Whether to traverse into objects as strings.
 | 
						||
                            If `True`, any non-compatible object will first be

                            converted into a string and then traversed into.
 | 
						||
                            The return value of that path will be a string instead,
 | 
						||
                            not respecting any further branching.

                            If no `default` is given and the last path branches, a `list` of results
 | 
						||
                            is always returned. If a path ends on a `dict` that result will always be a `dict`.
