What you describe feels very true for constructing a green diff containing lots of new code being added to a code base.

Being able to juggle text really comes into its own when you now have to move it around from one module into many, appease the linters, search-for then factor-out a common pattern, or rewrite your idea in place without breaking it. These are all things we do to take code from the “it works” stage to the “it’s correct” stage, namely self documenting modular code that is human as well as machine readable.

Vim makes light work of the back breaking chores involved with code gardening, which indeed bears little resemblance to programming.
