fare-mop has a few simple utilities relying on the MOP.
It depends on CLOSER-MOP for portable MOP access.
The main utilities are:
class mixin to give you a useful PRINT-OBJECT method for free
a simple PRINT-OBJECT function you can use it without the mixin
(useful when you don't want to change the class hierarchy of
some library you're using, but still want to simply inspect objects
and/or define a PRINT-OBJECT method on them).
a utility used by the above function, to collect a p-list
describing the slots bound in an object
a way to customize which slots get printed by SIMPLE-PRINT-OBJECT-MIXIN
Other utilities include:
a utility for "copying" objects by calling make-instance with
the "same" initialization arguments as an original objects,
plus overriding keyword arguments.
Useful for experimenting with a pure functional OO style.
Not for use where performance is important.
See documentation strings for details.
