Performs an element by element swap of the elements in 2 sequences.

[*Return type]: `void`
[*Precondition]: `__size__(seq1) == __size__(seq2)`
[*Semantics]: Calls `swap(a1, b1)` for corresponding elements in `seq1` and `seq2`.

[heading Example]
__vector__<int, std::string> v1(1, "hello"), v2(2, "world");
swap(v1, v2);
