Instances
---------
- primitive procedure: class-of value
Return the GOOPS class of any Scheme VALUE.
- primitive procedure: instance? object
Return `#t' if OBJECT is any GOOPS instance, otherwise `#f'.
- procedure: is-a? object class
Return `#t' if OBJECT is an instance of CLASS or one of its
subclasses.
Implementation notes: `is-a?' uses `class-of' and
`class-precedence-list' to obtain the class precedence list for OBJECT.
