I support the general idea of this proposal. It fits in our charter,
fills a real need, and is well enough specified to be considered.
However, the form of the proposal needs some more work.
- The name should probably be changed to something like
"SEQUENCE-FUNCTION-CONSING" to come to fit our naming convention.
As Larry said about another recent proposal, I doubt that you
could find "ELIMINATE" in CLtI and even you could it probably
wouldn't point to sequence functions.
- I'd suggest "SEQUENCE-FUNCTION-CONSING:TARGET-KEYWORDS" as a
- The proposal text should be rewritten as if it were the new parts
of the manual/standards document. I'd certainly understand some
abbreviation to keep from having to rewrite the whole sequence
chapter and a large part of the list chapter.
- The CONCATENATE and APPEND additions should either be moved into
the proposal section or into a second issue (which I would probably
All-in-all, this has moved from what I remember as more a philosophical
statement than a cleanup proposal to something that I think we can,
and should, pass unless we are prepared to "depreciate" the sequence
The main objection to this proposal seems to be Scott's belief that
LOOP can and will replace the sequence functions for most purposes. I
half agree in that: while I don't think replacing sequence functions by
LOOP is a good thing, I do think that replacing them by OSS would be
good. The critical difference is that OSS provides the functional
view of these operations that is important for some programming
styles. You could say that it comes back down to C versus Lisp again;
if I have to write everything as DO-loops, why am I using Lisp?
