Not quite, Gavin. You have to assign the value of unname back:
> z <- structure(2, names="a")
> unname(z)
[1] 2
> z
a
2
> zz <- unname(z)
> zz
[1] 2
> names(z) <- NULL
> z
[1] 2

"Men by nature long to get on to the ultimate truths, and will often
be impatient with elementary studies or fight shy of them. If it were
possible to reach the ultimate truths without the elementary studies
usually prefixed to them, these would not be preparatory studies but
superfluous diversions."
