Tidying of CL files; make docstrings read better, remove commented-out code 2010-05-30 Aidan Kehoe <kehoea@parhasard.net> * cl.el: Remove extraneous empty lines. Remove the commented-out Lisp implementation of #'last, #'copy-list. Remove #'cl-maclisp-member. (acons, pairlis): Have the argument list reflect the docstring for these functions. * cl-macs.el (defun*): Have the argument list reflect the docstring. Document the syntax of keywords in ARGLIST. (defmacro*): Have the argument list reflect the docstring. Document &body, &whole and &environment. (function*): Have the argument list reflect the docstring. (loop): Have the argument list reflect the docstring. (eval-when, dolist, dotimes, do-symbols, flet, labels, macrolet, symbol-macrolet): Specify the argument list using the arguments: (...) syntax. (define-setf-method, rotatef, defsubst*): Have the argument list reflect the docstring. (letf, letf*): Specify the argument list using the arguments: (...) syntax. (svref, acons, pairlis): Add compiler macros for these functions. * cl-extra.el: Remove the commented-out Lisp implementation of #'equalp. If we want to look at it, it's in version control. (cl-expt): Remove this. The subr #'expt is always available. Call #'cl-float-limits at dump time. Remove the commented-out Lisp implementation of #'subseq. (concatenate): Use (error 'invalid-argument ...) here, if TYPE is not understood. (list-length): Don't manually get the length of a list, call #'length and return nil if the list is circular. * byte-optimize.el (equalp): This needs byte-optimize-binary-predicate as its optimizer, as do the other equality predicates.
