-If you specify a map and a complete set of indices (of the correct types) on the left side of an assignment statement, you set a single element.
 {{CodeSample
 |code=<syntaxhighlight>
 int [item] my_pricelist;
-my_pricelist[ $item[ pail ] ] = 1000;
+int [item] new_pricelist;
 </syntaxhighlight>}}
 If you specify a map and a prefix of indices (of the correct type), you directly set one of the intermediate maps, a "slice".

Assignments: Mention aggregate literal

			You can initialize an entire aggregate with an ''aggregate literal''. For example:

			{{CodeSample
			\|code=<syntaxhighlight>
			int[item] my_pricelist = { $item[bum cheek]: 404,
			$item[red button]: 100,
			$item[red balloon]: 100000 };
	</syntaxhighlight>}}		</syntaxhighlight>}}
