No. It doesn't apply to constuctors, because ctors don't have names. (That's an odd provision of the standard introduced to make some explanations easier.) When you declare, define, or invoke a ctor, you do it by writing the name of the class. But that isn't the name of a ctor, and if you look up the class name in the class, you will not find a ctor. >is it legal to do this ? >class X > { > char X; > }; No. Chapter 9 paragraph 13 says ============================= If T is the name of a class, then each of the following shall have a name different from T: -- every data member of class T; -- every member of class T that is itself a type; -- every enumerator of every member of class T that is an enumerated type; and -- every member of every anonymous union that is a member of class T. ============================= That paragraph would seem to allow to allow function members having the name of the class, but such a function must be a ctor. -- Steve Clamage, stephen.clamage@sun.com --- [ comp.std.c++ is moderated.
