The ARM specifies that the left operand is not evaluated in such cases.</font></p>
<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207003"> </a><font size=2 face=Courier><strong>enum</strong></font> types can contain values larger than can be contained in an <font size=2 face=Courier><strong>int</strong></font>.</font></p>

<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207007"> </a>Argument-dependent (Koenig) lookup of function names is implemented.</font></p>
<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207008"> </a>Class and function names declared only in unqualified friend declarations are not visible except for functions found by argument-dependent lookup.</font></p>

<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207010"> </a>Function-try-blocks, that is, try-blocks that are the top-level statements of functions, constructors, or destructors, are implemented.</font></p>
<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207011"> </a>Universal character set escapes (for example <font size=2 face=Courier><strong>\uabcd</strong></font>) are implemented.</font></p>
<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207012"> </a>On a call in which the expression to the left of the opening parenthesis has class type, overload resolution looks for conversion functions that can convert the class object to pointer-to-function types, and each such pointed-to "surrogate function" type is evaluated alongside any other candidate functions.</font></p>
<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207013"> </a>Dependent name lookup in templates is implemented. Nondependent names are looked up only in the context of the template definition. Dependent names are also looked up in the instantiation context, via argument-dependent lookup.</font></p>
<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207014"> </a>Value-initialization is implemented. This form of initialization (added in TC1) is indicated by an initializer of "<font size=2 face=Courier><strong>()</strong></font>" and causes zeroing of certain POD-typed members, where the usual default-initialization would leave them uninitialized.</font></p>
<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207015"> </a>A partial specialization of a class member template cannot be added outside of the class definition.</font></p>
<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207016"> </a>Qualification conversions may be performed as part of the template argument deduction process.</font></p>
<p>  <font size=2  face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1207017"> </a>The <font size=2 face=Courier><strong>export</strong></font> keyword for templates is implemented.</font></p>
