Iterating through a range of ints in ksh?

Question

How can I iterate through a simple range of ints using a for loop in ksh?

For example, my script currently does this...

for i in 1 2 3 4 5 6 7
do

ksh93, Bash and zsh all understand C-like for loop syntax:

for ((i=1; i<=9; i++))
do
    echo $i
done

Unfortunately, while ksh and zsh understand the curly brace range syntax with constants and variables, Bash only handles constants (including Bash 4).
