> Developers say they want "visual programming", which makes you think "oh, let's replace if and for". But nobody ever made a flow chart to read for (i in 0..10) if even?(i) print(i).

I'm not convinced by this particular example. Wouldn't a visual programming language just represent the logic here as a pipeline connecting two more atomic operations: you'd have a visual representation where you pipe the (0..10) range through a function that filters for even values, and then pipe the result to a print function.
