Why not use the original noweb in the first place? You can even
maintain Sweave files with it, the Sweave latex syntax was written for
exactly that purpose ...

ESS supported noweb before Sweave existed. In fact the emacs noweb
mode was the main reason I chose that syntax for Sweave, and the latex
syntax was added lateron because some people write whole packages using
noweb and would have had a syntax conflict in their vignettes.
