Simulink should be included in the list?

All this "block programming languages" look promising, abstraction by black-boxing, doing boxes of boxes... I wonder if the implementations are bad, they are badly used, or the paradigm just does not work...

One thing to take into account, is that those things are typically used by people who have no idea how to program and abstract things. Maybe if somebody is good ad programming would not do a mess out of it; but then (s)he could just go ahead and write code. so.....

I must agree, LabView is terrible, not just because of that, but updates break everything, licensing, etc... just PITA
