That is usually true, but that means that the desire to mutate 
the codebase is a challenge when moving away form textual 
representation. So creating more structured tools is quite 
demanding. That was my point.

For dataflow I think it often is just as easy to do it visually, 
but therein is the key issue you need a variety of 
representations depending on how you mutate your code, whereas 
with plain text you can do with just one representation.
