I have installed Icon on the axiom-developer.org server and it
seems like a nice neat little language ... but I am sure Tim
will say: "Oh horrors, yet another programming language!" :)

I have also build noweb this way (partly because I was at one
time very interested in the filter to convert from LaTeX to
HTML) and I agree that the version of noweb that uses the
icon library is much faster. I also hacked a while on the
LaTeX to HTML code written in Icon, but eventually I abandoned
that approach in favour of the current pamphlet file support
on MathAction that does not involve conversion of LaTeX to
HTML.
