To get each element of a pair:

Use the [pair->get] method. Since the size of a pair is always 2 this tag only works with an index of 1 or 2. The following example loops through the elements of a pair using the [pair-size] method (which returns 2) and outputs them using the [pair->get] method.

Code

var( myPair = pair('first', 'second') )

loop($myPair->size) => {^
     'Element '+loop_count+' is '+$myPair->get(loop_count)+'\n'
^}

Result

Element 1 is first
Element 2 is second
