From NEWS in the Guile source code: ** Applicable struct support One may now make structs from Scheme that may be applied as procedures. To do so, make a struct whose vtable is `<applicable-struct-vtable>'. That struct will be the vtable of your applicable structs; instances of that new struct are assumed to have the procedure in their first slot. `<applicable-struct-vtable>' is like Common Lisp's `funcallable-standard-class'. Likewise there is `<applicable-struct-with-setter-vtable>', which looks for the setter in the second slot. This needs to be better documented. For a not-very-simple example, see modules/oop/gooops.scm in Guile's source code. I don't know any simple examples. Greetings, Maxime.
