Improve the implementation, documentation of #'labels, #'flet.
lisp/ChangeLog addition:
2011-09-07 Aidan Kehoe <kehoea@parhasard.net>
* bytecomp.el:
* bytecomp.el (for-effect): Move this earlier in the file, it's
referenced in byte-compile-initial-macro-environment.
* bytecomp.el (byte-compile-initial-macro-environment):
In the byte-compile-macro-environment definition for #'labels, put
off the compiling the lambda bodies until the point where the rest
of the form is being compiled, allowing the lambda bodies to
access appropriate values for byte-compile-bound-variables, and
reducing excessive warning about free variables.
Add a byte-compile-macro-environment definition for #'flet. This
modifies byte-compile-function-environment appropriately, and
warns about bindings of functions that have macro definitions in
the current environment, about functions that have byte codes, and
about functions that have byte-compile methods (which may not do
what the user wants at runtime).
* bytecomp.el (byte-compile-funcall):
If FUNCTION is constant, call #'byte-compile-callargs-warn if
that's appropriate, giving warnings about problems with calling
functions bound with #'labels.
* cl-macs.el:
* cl-macs.el (flet):
Mention the main difference from Common Lisp, that the bindings
are dynamic, not lexical. Counsel the use of #'labels, not #'flet,
for this and other reasons. Explain the limited single use case for
#'flet. Cross-reference to bytecomp.el in a comment.
* cl-macs.el (labels):
Go into detail on which functions may be called from
where. Explain how to access the function definition of a label
within FORM. Add a comment cross-referencing to bytecomp.el.
man/ChangeLog addition:
2011-09-07 Aidan Kehoe <kehoea@parhasard.net>
* cl.texi (Function Bindings):
Move #'labels first, describe it in more detail, explaining that
it is to be preferred over #'flet, and explaining why.
Explain that dynamic bindings with #'flet will also not work when
functions are accessed through their bytecodes.
