val create : Symbol.t -> Core_kernel.Source_code_position.t -> ?docstring:string -> hook_type:'a Hook_type.t -> 'r Returns.t -> ('a -> 'r) -> 'a t

create here return_type symbol f defines an emacs function named symbol that runs f when called. It returns an 'a t usable for modifying hooks.

val create_with_self : Symbol.t -> Core_kernel.Source_code_position.t -> ?docstring:string -> hook_type:'a Hook_type.t -> 'r Returns.t -> ('a t -> 'a -> 'r) -> 'a t

create_with_self here return_type symbol f works the same as create, except that the 'a t it returns is also passed as an argument to f.

This is useful, for example, if f wants to remove itself from a hook once it is called.
