Issue with incrementing variable by 1

[sts10]

I might be missing something, but when I throw this in the playground

i = 0 
print i 
i = i + 1
print i

I get

0
2

I would expect

0
1

I got here after having some issues with a for loop at the end of this little script.

Ah, i += 1 works as expected, it seems.

This should be fixed. It was working inside function blocks before, this fix is for the main block.
