// (1)
json_pointer operator/(const json_pointer& lhs, const json_pointer& rhs);

// (2)
json_pointer operator/(const json_pointer& lhs, string_t token);

// (3)
json_pointer operator/(const json_pointer& lhs, std::size_t array_idx);

1. create a new JSON pointer by appending the right JSON pointer at the end of the left JSON pointer
2. create a new JSON pointer by appending the unescaped token at the end of the JSON pointer
3. create a new JSON pointer by appending the array-index-token at the end of the JSON pointer

lhs (in) : JSON pointer

rhs (in) : JSON pointer to append

token (in) : reference token to append

array_idx (in) : array index to append

1. a new JSON pointer with rhs appended to lhs
2. a new JSON pointer with unescaped token appended to lhs
3. a new JSON pointer with array_idx appended to lhs

1. Linear in the length of lhs and rhs.
2. Linear in the length of lhs.
3. Linear in the length of lhs.

??? example

The example shows the usage of `operator/`.
 
```cpp
--8<-- "examples/json_pointer__operator_add_binary.cpp"
```

Output:

```json
--8<-- "examples/json_pointer__operator_add_binary.output"
```

1. Added in version 3.6.0.
2. Added in version 3.6.0. Changed type of token to string_t in version 3.11.0.
3. Added in version 3.6.0.
