While the smiley might cover the first sentence as well as the second, 
I would like to point out that there are certainly situation when you
need a vector, even if you want to write your programs
functionally. 

But more interesting, isn't a good practice to use vectors for data in 
order to avoid cons'ing? I have read from time to time (recently in a
post on this list by Tanel Tammet, the author of Hobbit) that
cons'ing is bad if you want good performance, and my interpretation is 
that you need vectors instead of pairs to group data.
