Pass Command Into FOR Loop and Read Current Value of i

Is there a way I can call splib:for with a command that takes a numeric value, and have the command read from i
In my specific example, I want to pass a function that applies to every slot of the inventory. stop = 36
The command applying to every inventory slot takes a slot value (in this case, the value of i), and cmd, which is a command to apply to each slot.
splib:for
# Create objective
scoreboard objectives add splib dummy

# Call recursive helper
$function splib:for_loop { stop: $(stop), cmd: "$(cmd)" }

# Remove objective
scoreboard objectives remove splib

splib:for_loop
# if $i in $range
#   run command
$execute if score i splib matches ..$(stop) run $(cmd)

# $i++
scoreboard players add i splib 1

# if $i in $range
#   run $self
$execute if score i splib matches ..$(stop) run function splib:for_loop { stop: $(stop), cmd: "$(cmd)" }
