This approach is superior to bgl_named_params in part because it avoids undue coupling and dependency in a library design. That coupling is discussed in depth in this excerpt from C++ Template Metaprogramming (http://www.boost-consulting.com/mplbook): [snipped] This coupling could be avoided by using an overloaded operator to combine the arguments, for example: f(slew(.799) | name("z")); An advantage of this method is that it avoids the need for the forwarding functions.
I was just going over the library and have a related question. Is there a rational as to why the forwarding functions where used instead of overloading the "," operator?
What did you have in mind? f(slew = .799, name = "z") ^ The comma above will never be treated as an operator. It's just the way C++ works -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
