+ <p>
+ Array elements can be accessed using either square brackets or a dotted
+ index notation, e.g. the following are equivalent
+ <source>arr[0]
+arr.0</source>
+ The same holds true for lists.
+ </p>
+ <p>
+ For a map, the syntax is very similar, except the 'index' is an object,
e.g.
+ the following are equivalent.
+ <source>aMap['key']
+aMap.get('key')</source>
+ Please note that the index does not have to be a string, and
+ that the string usage above is just one possible option.
