A lot of the things _I_ do in Photoshop could probably be done more efficiently in a CLI (read DSL) than a GUI (and enable me to create and manage reusable components in a better way - some kind of mixins for example). Now, a lot of what I do is adding (and tweaking!) effects and filters bound to shapes, selections (most often based on shapes) and layers, it would be harder to create an efficient CLI to _draw_ arbitrary shapes, but I don't used Photshop for that anyway.
