Yes, I intentionally omitted this in order not to overload the
readers, nevertheless anyone who tries the five problems will
naturally notice this generalization.
As for Colin's objections against writing tight code, he is partially
right. I typically try to make my code readable by including
delimiting empty lines, or by placing an expression on many lines and
aligning its components vertically, so that it is visually intuitive
and doesn't require horizontal scrolling.
This said, there would be no great formulas (remember Einstein's e =
mc^2) if we always tried to expand and make them more readable.
Nobody would be able to remember them...
$vSeq[index-of($vSeq,.)[2]]
is a formula.

Yes, it's an amusing one. It's the first time I have ever come across a
useful way of using a filter expression where the predicate evaluates to an
integer that's variable, ie. a function of the context item.
I quite like the fact that this generalizes.
$vSeq[index-of($vSeq,.)[$i]]
produces a list of the (distinct) values in $vseq that have at least $i
occurrences.

Dimitre is deceptively good.
Please allow some time to study the link.
