I would be interested in programming languages that exhibited abstractions or metaphors that reflected the human language they were written in (or at least its culture).
The Western musical model (well tempered scale, etc) is prevalent worldwide but other musical approaches are still quite strong and doing well.
But I don't see that in this wikipedia entry. Could programming be so mathematical that all languages use the same metaphors, rather than ones somehow specifically entangled with English? I only speak indo-european languages so I have a hard time imagining truly "foreign" programming approaches.
