I noticed a bug with the for loop.

The following works
{for $i = 1000; $i >= 1; $i --}

The following does not work

{for $i = 1000 to 1}

The for loop does not support going backwards when just specifying "to"

try with step=-1

That worked, but if that is missing should it be expected behavior to work that way?

This use to work in the Smarty3.0rc3 and I had to change around on a lot of websites to get it to work.

I compared the versions and see this code was replaced:

Smarty3.0rc3

uwe can probably answer this better, but it is probably a better idea to not assume a step value based on the from->to values. No different than php for(), there is no assumption of a negative step value, you have to supply it. for consistency, step is always 1 if not supplied.

We did have a couple of issues determining the step value automatically from the from->to values. Remember the later can be variables.

For that reasion the code was changed.
