
Concept: Hooks
Hooks are used throughout gwave to provide a convenient mechanism for
user callbacks on particular events. Fundamentally, a hook is just a
variable that contains a list of procedures that are called in order
when the relevant event occurs. However, several convenience macros
are provided for manipulating hooks; see `add-hook!', `remove-hook!',
`reset-hook!', and `run-hook'.
