Getting back to the Web Module, the following could help a lot if there were in the core or as a 'core' downloadable bundle :
- DBI - ORM system - Caching system - Sessions (server side cookies) - XML parser - JSON parser I guess that it will be fair enough for actual web apps. templating system that could be hooked or using flex points, classes related to CRUD,scaffolding,input filtering, unit testing could be a plus but could sound more like a framework than a programming language^^; I've certainly forgotten many things but that's what came up at the moment.
