Rutils ?
I was excited to try this out when I came across it ... but it looks like (today!) the github repo is not in a compilable state, at least on Allegro CL. CL-USER(44): (ql:quickload 'rutils) To loa…

I came across this paper (actually a literate haskell document, pretty cool!) from MIRI. (What's MIRI ? I suppose someone finally convinced the "Singularity Institute" they had a terribl…
Defstruct and Defclass as macros
The SBCL version (macroexpand-1 '(defstruct spoint (x y))) (PROGN (SB-KERNEL:WITH-SINGLE-PACKAGE-LOCKED-ERROR (:SYMBOL 'SPOINT "defining ~…
Fixing a SLIME/Swank version problem
