Tests are better than impressions. Sometimes they match though.

$ time for ((i = 0; i <= 1000000; i++)); do j=$i; k=$j; m=10;
n=foobarbazqux; p=1000000; q=$n; r=$k; s=$i$j$k$m$n$p$q$r; done

real 0m24.542s
user 0m23.440s
sys 0m0.199s
$ time for ((i = 0; i <= 1000000; i++)); do j=$i k=$j m=10 n=foobarbazqux
p=1000000 q=$n r=$k s=$i$j$k$m$n$p$q$r; done

real 0m17.087s
user 0m16.679s
sys 0m0.129s

But at about 8 microseconds per iteration I don't think it's enough of a
difference to choose it for speed alone.
