While your research might be through I think it misses the purpose of most programming languages: Building Software. Or even more precise: solving problems.

As most software nowadays also seems badly designed the need for tools and languages that allow rapid development and rapid course changes while building a product might have a higher need.

Having the perfect plan and being allowed to follow it along for as long as it takes only deserves the perfect language of course. But, alas, when is it like that?
