I know this isn't exactly the same thing, but I just wanted to mention a 
successful(large code/user base) visual programming system for C++, 
Blueprints:
https://docs.unrealengine.com/latest/INT/Engine/Blueprints/GettingStarted/

It is a scripting layer between hot reloadable C++ classes. It is done 
via a horrible macros with all the expected problems: it can't parse 
everything, no templates for instance, making it yet another 
(sub)language you need to learn.

But still, I think there is something of value here. Being able to hook 
up code and tweak everything visually is great.
