Make #'equalp more compatible with CL; add a compiler macro, test & doc it. lisp/ChangeLog addition: 2009-11-08 Aidan Kehoe <kehoea@parhasard.net> * cl-extra.el (cl-string-vector-equalp) (cl-bit-vector-vector-equalp, cl-vector-array-equalp) (cl-hash-table-contents-equalp): New functions, to implement equalp treating arrays with identical contents as equivalent, as specified by Common Lisp. (equalp): Revise this function to implement array equivalence, and the hash-table equalp behaviour specified by CL. * cl-macs.el (equalp): Add a compiler macro for this function, used when one of the arguments is constant, and as such, its type is known at compile time. man/ChangeLog addition: 2009-11-08 Aidan Kehoe <kehoea@parhasard.net> * lispref/objects.texi (Equality Predicates): Document #'equalp here, as well as #'equal and #'eq. tests/ChangeLog addition: 2009-12-31 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: Test much of the functionality of equalp; add a pointer to Paul Dietz' ANSI test suite for this function, converted to Emacs Lisp. Not including the tests themselves in XEmacs because who owns the copyright on the files is unclear and the GCL people didn't respond to my queries.
