It might not be easy to internally convert a for loop to a while loop, 
it may require a completely separate loop.

That shortcut still redeclares the variable, it is just a typing

to assign to it. That is the exact reason I added a #set keyword in my 
patch, so you can use a separate keyword for modifying variables.
