I did standard interface, standard API, and used a dynamic ring as a
model
https://lispblivet.sx/code/?p=emacs.git;a=blob_plain;f=emacs/local/elisp/borg-repl.el;hb=refs/heads/master
the idea is impose a standard interface with bindings that map to
buffer local function pointers.
for a mode API side do a dynamic ring with rotation with some nice
facades.
