Make it possible to silence warnings issued when #'mapcar's result is discarded. lisp/ChangeLog addition: 2009-10-19 Aidan Kehoe <kehoea@parhasard.net> * bytecomp.el (byte-compile-default-warnings): Add two new warning types, discarded-consing (basically use of mapcar instead of mapc where its result is discarded) and quoted-lambda (use of a lambda expression quoted as data in a function context). (byte-compile-warnings): Document the new warnings. (byte-compile-fset, byte-compile-funarg): Implement the quoted-lambda warning option. (byte-compile-mapcar): Renamed to byte-compile-maybe-mapc. (byte-compile-maybe-mapc, byte-compile-maplist): Implement the discarded-consing warning option. Add more functions that should be compiled using byte-compile-funarg, notably mapvector, mapc-internal, map-char-table. * cl-macs.el (mapcar*): If we know at compile time that there are no CL options being used, use the mapcar subr, not the byte-coded function.
