Reimplement a few GNU functions in terms of CL functions, subr.el 2011-06-19 Aidan Kehoe <kehoea@parhasard.net> * cl-macs.el: * cl-macs.el (assoc-ignore-case, assoc-ignore-representation): * cl-macs.el (member-ignore-case): New compiler macros. * subr.el (assoc-ignore-case): * subr.el (assoc-ignore-representation): * subr.el (member-ignore-case): * subr.el (split-path): * subr.el (delete-dups): Reimplement a few GNU functions in terms of their CL counterparts, for the sake of circularity checking and some speed; add type checking (used in interpreted code and with low speed and safety checking) for the sake of revealing incompatibilities when developing. * subr.el (remove-hook): There's no need for flet here, an explicit lambda is enough.
