This is not legal. The name of the constructor should be the same as the name of the class.

Should be private? How this code even compiles is beyond me.

1 example of call is

x.template GetSpot( 5 );

GetSpot? I only see Get.

I apologize, I didn't replace all names to make code more readable... It was just P ... that was P's ctor... It's Get, not GetSpot x.template Get( 5 ); I've added to default argument to the out-of-class definition as well and then it works... does it make any sense? H
