<paragraph>Primary expressions are divided between <non_terminal where="14.5.10.2">array-creation-expression</non_terminal>s and <non_terminal where="14.5">primary-no-array-creation-expression</non_terminal>s. Treating <non_terminal where="14.5.10.2">array-creation-expression</non_terminal> in this way, rather than listing it along with the other simple expression forms, enables the grammar to disallow potentially confusing code such as <code_example><![CDATA[
|
||
|
|
object o = new int[3][1];
|
||
|
|
]]></code_example>which would otherwise be interpreted as <code_example><![CDATA[
|
||
|
|
object o = (new int[3])[1];
|
||
|
|
]]></code_example></paragraph>
