More test cases to be added

{#groups}
 {@i18n key="three" text="testing for : value is: {skills[.]}......."/}  
 {@i18n key="three" text="testing for : value is: {skills[$idx].name}......."/}
 {@i18n key="three" text="testing for : value is: {skills[$len]}......."/}
{/groups}

This allows random access of an array element outside the current loop
say 2 arrays groups and skills exist and we want to get the skills name of iteration "i" in the groups
