(synopsis "Extension of CLOS generic function invocation")
(description
"Filtered functions provide an extension of CLOS generic function
invocation that add a simple preprocessing step before the actual method
dispatch is performed and thus enable the use of arbitrary predicates for
selecting and applying methods. See
@url{http://www.p-cos.net/documents/filtered-dispatch.pdf} for a paper that
introduces and explains filtered functions in detail.")
