   You can use the FOREACH construct.

   Yes, "foreach" is the common idea, but you can also use the function "get_type()" to show the length. Here is an example:
   {def $somearray=...}
   {def $length=$somearray|get_type()}
   {for 0 to $length as $counter}
   {$somearray[$counter]}
   {/for}
   {undef}
   This is more helpful if you want to access the neighbour elements of the actual element, for example. If you do not need a counte, "foreach" is easier to use.
