(fini-mixin ..body)
  body: zero or more forms
C

Defines a mixin finalizer method.

When an object is killed, its fini method is invoked, followed by the fini-mixin method for each of its mixins, in order from right to left.

fini-mixin is not a wrapper method, so there's no need to call @base. Also note that it does not have a parameter list.
