-- Mapping functions (take a list and do something to each element):

map_prop ({o...},prop) => list of o.(prop) for all o

map_verb ({o...},verb[,args) => list of o:(verb)(@args) for all o

map_arg ([n,]obj,verb,{a...},args) => list of obj:(verb)(a,@args) for all a

-- Association list functions --

An association list (alist) is a list of pairs (2-element lists), though the following functions have been generalized for lists of n-tuples (n-element lists). In each case i defaults to 1.

assoc (targ,alist[,i]) => 1st tuple in alist whose i-th element is targ

iassoc (targ,alist[,i]) => index of same.

assoc_prefix (targ,alist[,i]) => ... whose i-th element has targ as a prefix

iassoc_prefix(targ,alist[,i]) => index of same.

slice (alist[,i]) => list of i-th elements

sort_alist (alist[,i]) => alist sorted on i-th elements.
