-It felt like a language that wanted to be handled like physical tokens, where you drag words around, reorder them, insert one between two others, and treat the code as something you can literally move with your hands. I never prototyped that idea, but it never went away.

-The implication of that kind of free drag-and-drop editing is that you can accidentally land in a structurally invalid program. The grid sketch was my answer: a constrained layout that only lets you build valid programs.

On mobile I was dissatisfied with open editing, because it seemed like you want constrained, structural editing.
