This minor mode turns your typing of camelCase into snake_case or listp-case or else.
When you enable it, type “anVariable” results in “an_variable” or “an-variable”.
You can customize the delimiter and add your rules of when to modify the input and when to not.
Demonstration:
You need to configure camelsnake-mode because camelsnake-mode doesn’t do anything
by default unless you enable it for each major mode.

Mind that this function is called in `post-self-insert-hook', so don't put heavy stuff in it.")
