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.
