    Is it possible to add new elements (a new pair key/value) to an existing hash?

      Yes, it is possible to add items to an existing hash (though the syntax is crabbed). The following example shows how items can be added:

      {def $items=hash('bar','boff')}
 
{set $items=$items|merge(hash('foo','some text','ping','poot'))}
 
foo = {$items['foo']}<br/>
ping = {$items['ping']}<br/>
bar = {$items['bar']}


      The example initialises a hash, and then adds two extra pairs to it using the merge operator.

        and, how to replace a value?

        {def $items = hash('aaa', 'A')}

        {$items.aaa='B'}

        it gives me error.
