No, Parameter List is not a class template but its method set is  
templated

	class ParameterList {
		
		...
		template<typename T>
   		void set( string const& name, T const& value, std::string const&  
docString = "");
		...

And yes I could create a method to use only a limited number of types  
but I would like to pass a python object in as "value" and have boost  
try and extract a c++ object to pass to set.
I have no control over this class, it is part of a software package.
