Drop cl-macro-environment in favour of byte-compile-macro-environment. lisp/ChangeLog addition: 2011-09-04 Aidan Kehoe <kehoea@parhasard.net> * bytecomp-runtime.el: * bytecomp-runtime.el (byte-compile-macro-environment): Moved from bytecomp.el. * bytecomp.el: * bytecomp.el (byte-compile-initial-macro-environment): Add implementations for #'load-time-value, #'labels here, now cl-macs respects byte-compile-macro-environment. * bytecomp.el (byte-compile-function-environment): * bytecomp.el (byte-compile-macro-environment): Removed. * bytecomp.el (symbol-value): * bytecomp.el (byte-compile-symbol-value): Removed. * cl-extra.el (cl-macroexpand-all): * cl-macs.el: * cl-macs.el (bind-block): * cl-macs.el (cl-macro-environment): Removed. * cl-macs.el (cl-transform-lambda): * cl-macs.el (load-time-value): * cl-macs.el (block): * cl-macs.el (flet): * cl-macs.el (labels): * cl-macs.el (macrolet): * cl-macs.el (symbol-macrolet): * cl-macs.el (lexical-let): * cl-macs.el (apply): * cl-macs.el (nthcdr): * cl-macs.el (getf): * cl-macs.el (substring): * cl-macs.el (values): * cl-macs.el (get-setf-method): * cl-macs.el (cl-setf-do-modify): * cl.el: * cl.el (cl-macro-environment): Removed. * cl.el (cl-macroexpand): * obsolete.el (cl-macro-environment): Moved here. Drop cl-macro-environment, in favour of byte-compile-macro-environment; make the latter available in bytecomp-runtime.el. This makes byte-compile-macro-environment far less useless, since previously code that used cl-macs would ignore it when calling #'cl-macroexpand-all. Add byte-compiler-specific implementations for #'load-time-value, #'labels. The latter is very nice indeed; it avoids the run-time consing of the current implementation, is fully lexical and avoids the run-time shadowing of symbol function slots that flet uses. It would now be reasonable to move most core uses of flet to use labels instead. Non-core code can't rely on print-circle for mutually recursive functions, though, so it's less of an evident win.
