Dear Leslie,

order functions to map over lists, right?»

I assume you are not familiar with Mathematica, right?

Although it may seem that i'm chiding you, but in discussions, one
should be clear about what one knows and what one doesn't know, as
opposed to stalwartly acts like young college boys do.

If you have a question, _ask_ it earnestly, as opposed to throwing a
tangential exclamation or challenge.

Sure, we are all cocks — congenitally belligerent. But still,
especially in intellectual discourses, braven your way does not
advance you in the eyes of other men.

Now, to answer your question. In this thread, i spoke of list
manipulating functions in Mathematica. I have given out links to their
docs. If you want to know what are these and how easy or difficult it
is to emulate them by mapping functions to list, you can study the
links i gave. I don't think they are too hard to read even if you've
never seen Mathematica code.

Btw, speaking of mapping functions to lists... Mathematica has a whole
set of such functions. Map, MapThread, MapAt, Nest, NestList, Fold,
FoldList, FixedPoint, FixedPointList, Outer... all buildin. These are
really far more advanced in terms of their flexibility at mapping to
lists or recursion, far beyond any of CL, Scheme, or Haskell. (i'm
confident in this claim even i don't really know CL and Haskell)

So, if you have a question, ask. Ask means earnest. You can also ask
even specific questions. You need not necessarily be polite with me. I
judge messages by their content's quality and sincerity.

PS in case you think i'm being silly, yes i am. Y'know? tech geekers
behave asinine in newsgroups, so can i.
