> I'd like to see no-code UX patterns that losslessly map onto the underlying abstraction. That way you can use the UX pattern until it gets too tedious, and occasionally dip in-and-out of the code-view in a non-jarring manner.

What are you describing sounds a lot like Saleforce and other CRM systems. Often the code implementation get hidden away when it's not something native in the no-code solution. Then "magic" happens and you don't quite know why until you dig into the code again.
