This package provides a prefix \named to be used in TeX definitions so that
parameters can be identified by their name rather than by number, giving
parameters a semantic rather than syntactic meaning, making it easy to
understand long definitions. A usual definition reads: \def\SayHello#1{Hello,
\named\def\SayHello#[person]{Hello, #[person]!} and \named will figure out the
numbering of the parameters for you.
