 List data type:
-- When removing items from the condition stack may free cs_fors.
-- don't copy the list, use a list-watcher to adjust the item pointer when it's
-  deleted.
-- "for a in list"
-    Make copy of the list to avoid trouble when it changes.  As one big block?
-- "for [a, b] in [[1, 2], [3, 4]]"
-- support list generator: items are obtained with a function by index.
-    "range(1, 400, 2)" creates one.
-- == (same value) and "is" (same list)
-- add many functions:
-    call(func, list)		call function
-    keys(list)			list of all indexes 0 - (len(list) - 1)
-    repeat(list, count)		return list concatenated count times
-    concat(list1, list2)	return list1 and list2 concatenated
-    extend(list1, list2)	concatenate list2 to list 1
-    extend(list1, list2, idx)	prepend list2 before idx in list1
-    count(list, item)		nr of times item appears in list
-    index(list, item)		lowest index of item in list
-    pop(list[, idx])		removes item at idx (default: last)
-    pop(list, idx1, idx2)	removes items idx1 to idx2, returns them
+- add more functions:
     reverse(list)		reverses order
     sort(list[, func])		sort; func compares items
     getval(list, idx[, default])	get value at idx or default
