So it really is just a generalization of CDR

(conceptually, at least... concretely, it copies!)

i would say it avoids a class of special cases you'd otherwise need to check for, and just makes logical sense

similar to how (+) is 0

the length of a subsequence is always (- end start), whether or not start and end are equal

thanks for the clarification; I've been doing a lot of car/cdr iteration lately and that sort of jumped out as a "huh" moment

pjb: Thanks for the clarification ! That would indeed be a fun projet to add such a read-only feature

I'm surprised to learn that append doesn't copy the last list, but it does make sense

APPEND, like most lisp functions, prefers to get the job done with the fewest copies

APPEND could get confused if it tried to copy something that isn't a list, e.g. in (append '(1 2 3) 'a)

(or at least, as if it used COPY-LIST to copy.)

Why are older versions of quicklisp-installed packages kept around after upgrading?
9:12:04
madrik
By 'older versions', I meant the archives.

madrik: well, you can go back if the upgrade broke your software, or you can have different software on different versions of the quicklisp distribution

madrik: you can also use ql-dist:clean to clean them up

Xach: We've been running a "quickclasp" server to distribute stuff specific to clasp - it's been working well.

Anyone knows how to use this library? In particular, how to use #'digit? to parse a digit? https://github.com/Ramarren/cl-parser-combinators/blob/9c7569a4f6af5e60c0d3a51d9c15c16d1714c845/token-parsers.lisp

ah (monadic) parser combinators are powerful :)
