My first thought: maybe competitive programmers could find it useful, if it’s a way to reduce the amount of key presses needed to write their code? (At the very least, that’s a crowd that would be motivated enough to get accustomed to that way of writing code.)
Every year when I participate in advent of code, I have this thought: "wouldn't it be great to solve these problems directly from my phone?" (The puzzles unlock quite early morning in my timezone and opening my laptop at that time somehow annoys me.)
I have wondered many times if some structural editor with a bunch of high-level library methods (Dijkstra's, for instance) would actually give a good/fast experience for most days. I haven't had the time or interest yet to try and build something yet. But perhaps I should.
I'd love to get this to the point where add your own keybindings to structural edits, potentially very involved ones.
It's superficially not very different to a combination of vim macros, auto completes or templates in other editors but I think the end result could be interesting as the units of change would be more meaningful.
I think it's the same benefit of a hygienic macro system vs a source file manipulating version of meta programming.
