To make things clear, I am delighted that rather than telling the Wesnoth developers what we could, should, or would do, someone is actually doing something productive in terms of making an extensible programming language system for Wesnoth. Thank you for working on this! I hope it turns out well, and whole-heartedly support a quality implementation of this going into mainline.
