I think the inherent suckiness with visual programming is...
Imagine I was a consultant who offered to sit and watch over your shoulder and comment only on syntax issues. If you make a syntax mistake, I will help you fix it; "you need a closing paren here". I will also offer syntax tips constantly while you work; "looks like your going to create a list, first choose what you want the first item in the list to be". You should expect to be a little slower in exchange for these consultations I offer. Would you hire me?
These are essentially the tradeoffs offered by visual programming. Slower work for syntax level help. And visual languages often have some premium cost to them.
People doing significant programming don't need syntax level help.
