I'm working on static site generator written in Tcl that is nearing its 1.0 release. It aims to be featureful but self-contained and have reasonable defaults to allow you to quickly start working on a new website. You can find it at https://github.com/tclssg/tclssg.
I just created a tool to walk a wsdl definition to create a single contained xsd file for distribution to users of the wsdl.
With Tcl the tool was done in a couple of hours.
Recently I looked for a "TCLscript" targeting Javascript but I didn't find anything (under development at least).
The only strong players that I recognise in this market are Coffeescript, Typescript and Clojurescript. Probably there would be a market for "TCLscript" also.
Wow, there's a blast from the past. A friend of mine (Jesse Liley) built a cool device-mounting-thingy called MUT in Tcl a few years ago, for the Puppy Linux distro.
I've code algorithms for spellcheckers and text summarizers in Tcl. I've been using it for proof-of-concept data science/AI/machine learning stuff for years.
