Cl-CAR

Goal of this gist: make a drafty list of ideas for CDR (Common Lisp Document Repository) (see also Zenodo Community CDR)

Put the ideas (possibly with links) in the comments

Package locks

make-string-output-stream doesn't accept an existing string with a fill-pointer

Advising functions

There's no way to define your own (defun (compound name) ...)

sleep with sub-second precision

Already in the standard, my bad

symbol aliases

declaratively, through defpackage:

(defpackage #:pkg
  (:import-from #:alexandria
     #:unionf #:removef
     (#:line-up-last #:->>)
     (#:line-up-first #:->)))

Where the car is the original symbol and the cdr is the list of aliases

Another list

CLiki: Proposed Extensions To ANSI

from me:

It could be nice if digit-char could take a third argument for the alphabet

There should be a CDR for package-local nicknames. (see https://github.com/Gleefre/cdr-package-local-nicknames/ for a draft I wrote some time ago -- a rewrite is probably needed)

Structures should be less under-specified. For example slot-... functions should work on those (unless :type is vector or list); it should be possible to meaningfully use structure-class; there should be ensure-struct function.

[ until cl-car is fully up, will continue writing ideas here ]

There should be compiler-macro-let or similar.

I think it would be better to just create a discussion in cl-car

Maybe the title could be just "compiler-macro-let"
