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.
