Sorry, maybe it's simple, but nothing comes to my mind :)

Say, we have something like that

set one 1
set two 2
set three 3

set x {$one $two $three}

and x contains $one $two $three

how to make "1 2 3" using only the current value of x, in other words,
to force appropriate substitutions on this expression?
