Ok... you're off track here. :)
A series does not just have the sequence of elements. It also
keeps a position in the sequence.
>> b: ["Hello"]
== ["Hello"]
>> s: skip first b 2
== "llo"
>> insert tail s " world!"
== ""
>> s
== "llo world!"
>> b
== ["Hello world!"]
The first element of B and the value referred to by 'S are not
*exactly* the same value. They are two series values, referring to
the same sequence of elements, but at different positions.
Regards,
Gabriele.
