Precisely! The skip is far more general than just for this query.

Sounds like this is a good solution. This skip method should be useful in
other places too.

Till,
On further thought, I think I have a better solution -- one that is more
general and does not require any compiler support.
Add a method to the iterator of the form
int skip(int len);
The contract would be that skip tries to skip len items and returns len - n
as the return value where n is the number of items it could actually skip
(Can be < len, if it reached end-of-sequence).
The default implementation could be:
while(len-- > 0 && in.next() != null);
return len + 1;
The iterator of the Sequence could do this in a smarter way.
The second part is the use of skip in subsequence.
This will give us the speed improvement for the query.
What do you think?
