ViperCard – An open source re-creation and re-imagination of HyperCard
As for the problem with languages like HyperTalk and AppleScript being read-only, the solution isn't to change the syntax, it's -- wait for it -- AI! If Google can figure out what you want from a spoken free-form inquiry, then a smart interpreter should be able to figure out what you're trying to say in a line of code, even if you don't get the syntax quite right. And if your code is ambiguous, it can ask you confirm your intentions. Why haven't we seen more of this?
