Yeah, I think the endgame of visual programming tools is to just eliminate syntax errors.

You could probably conceive of C as a visual programming language if you spent long enough time. All of your keywords can be reduced to blocks, forcing people to insert the appropriate parameters. And once you allow people to define their own blocks, you're like a good portion of the way there.

The problem is that after a while, it is simply faster to type. The breadth of options available becomes too much to manage from menus and drag and drop interfaces. Already you're probably typing in some values and names. So you're constantly switching between keyboard and mouse.

At some point, the benefit of perfect syntax doesn't outweigh the loss of productivity from not being able to immediately use any construct the language makes available to you.
