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.
