I'd like to. For example, when I'm reading a file and something I read
changes the situation. I might be processing a series of which, at start
time, I can't know the top value.

Or, in your own example,

> sequence seqindex
> seqindex = {3, 5, 10, 21, 22, 40, 45, 50, 63}
> for i = 1 to length(seqindex)
>   seq2process[seqindex[i]] = <something>
> end for

What if <something> included the addition and/or deletion of elements from
sequindex, hence changing its length?

An excellent suggestion.

Anything that results in clearer syntax is bound to be useful.
