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, Deferring parsing of default arguments 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>());
};

Correct default argument deferral 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 .
