defer_defarg_parsing

Defers the parsing of default arguments in member functions.

  #pragma defer_defarg_parsing on | off  

To be accepted as valid, some default expressions with template arguments will require additional parenthesis. For example, the following listing results in an error message.

template<typename T,typename U> struct X { T t; U u; };
struct Y {

   // The following line is not accepted, and generates 

   // an error message with defer_defarg_parsing on.

   void f(X<int,int> = X<int,int>());

};

The following listing does not generate an error message.

template<typename T,typename U> struct X { T t; U u; };
struct Y {

   // The following line is OK if the default  

   // argument is parenthesized.

   void f(X<int,int> = (X<int,int>()) );

};

This pragma does not correspond to any panel setting. By default, this pragma is on.
