At this point, the new value of s:vars is just [ 1, 2 ] — no record is
kept of where the values came from.

If you had, instead, done

let s:vars = [ 's:vara', 's:varb' ]

(with quotes), then, of course,

for mvar in s:vars
echo mvar ':' eval(mvar)
endfor

would (IIUC) have displayed (not sent to the printer)

s:vara : 1
s:varb : 2

i.e., from the name you can retrieve the value, but not vice-versa.

Of course, the s: namespace means that all those operations have to be
done in the same script. Not in a different script, and not in
command-line mode.
