So, I have the following function:

Needs more print in your print debugging:
```d
writeln("tempcolor: ", tempcolor);
...
writeln("in tempcolor with j: ", j);
```
output:
```
tempcolor: 1
in tempcolor with j: 0
...
... numbers
...
tempcolor: 0
tempcolor: 0
tempcolor: 0
tempcolor: 0
tempcolor: 0
tempcolor: 0
tempcolor: 0
tempcolor: 0
tempcolor: 0
tempcolor: 1
in tempcolor with j: 0
```
I figured out something weird. The variable 'i' is passed by
reference, yet the variable 'i' of the loop isn't being
incremented by posfunc. I assume foreach creates a new i
variable at the start of each new loop. Swapping the original
loop with a while loop fixes the problem. Thank you very much
for trying to help.
