Fewer algorithmic complexity surprises, nicer errors, mapcarX(), maplist() src/ChangeLog addition: 2010-09-01 Aidan Kehoe <kehoea@parhasard.net> * fns.c (list_merge, list_array_merge_into_list) (list_array_merge_into_array): Avoid algorithmic complexity surprises when checking for circularity in these functions. (Freduce): Fix some formatting, in passing. (mapcarX): Drop the SOME_OR_EVERY argument to this function; instead, take CALLER, a symbol reflecting the Lisp-visible function that called mapcarX(). Use CALLER with mapping_interaction_error() when sequences are modified illegally. Don't cons with #'some, #'every, not even a little. (Fmapconcat, FmapcarX, Fmapvector, Fmapcan, Fmapc, Fmap) (Fmap_into, Fsome, Fevery): Call mapcarX() with its new arguments. (Fmapcan): Don't unnecessarily complicate the nconc call. (maplist): Take CALLER, a symbol reflecting the Lisp-visible function that called maplist(), rather than having separate arguments to indicate mapl vs. mapcon. Avoid algorithmic complexity surprises when checking for circularity. In #'mapcon, check a given stretch of result for well-formedness once, which was not previously the case, despite what the comments said. (Fmaplist, Fmapl, Fmapcon): Call maplist() with its new arguments.
