iota -- Generate a list of the integers from 0 to N-1 in order.
reverse-iota -- Generate a list of the integers from N-1 to 0 in order.
accumulate -- Repeatedly apply PROC to a current value and a member of L.
reduce -- Repeatedly apply PROC to a current value and a member of L.
append-map -- Do the same thing as map, but collect results with append, not cons.
filter -- Return a list of those elements of L for which PRED is true.
there-exists? -- Return true if PRED is true for at least one elements of L, otherwise false.
for-all? -- Return true if PRED is true for all elements of L, otherwise false.
and-map -- Apply PROC repeatedly, returning the first false value.
or-map -- Apply PROC repeatedly, returning the first true value.
list-index -- Return the integer position of OBJ in list L.
make-list -- Return a list containing N elements equal to the optional second argument.
map-in-order -- Process FIRST and the lists comprising REST as map would.
filter-map -- Process FIRST and the lists comprising REST as map would.
filter-list -- Like list, but ignore #f and unspecified values.
delete-duplicates -- Return a list that has the elements of L with duplicates omitted.
list-without-elem -- Return the list L with element E deleted.
repeat -- Builds a list of repeating values.
flatten -- Return LIST-OF-LISTS as a single flat list.
