Patches to that effect are welcome. Btw, most of the code for self-insert-command is in an internal function, so rewriting that in Lisp is unlikely to help people understand its internal hair. More importantly, most of the complicated parts of the C code cannot be rewritten in Lisp anyway, so only limited progress can be made this way, which will not make it easier to understand the core.
