Suppose you write your class so that '+' will provide addition and

the sequence library would be for you, you can't use it. You will
have to rewrite those function you need, in terms of a concat method
instead of '+'.
That also means that whatever sequence like functions you write
for this class, you can't use those functions for sequences in
general because in general, sequence don't have a concat method.
Do you have an example of where this would be useful?
Thanks.
