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):

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? -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com - 102708583/icq
