A new #blog post! This time, I’m exposing #CommonLisp #Lisp package-inferred systems as motivating harmful practices and making people’s life worse. Inside:

• Discipline and Wrong :use—it’s too easy to :use too much

• #IDE-less Reading—being impossible with package-inferred systems and their symbol mixing

• Packaging Hell

• Systems are Metadata, not Data—as a small ontological note

Lem editor news: it just got the one shortcut that makes me a 10x developer: `lisp-call-defun` bound (as in Slime) to C-c C-y.

Coincidentally, I assume, Abhijit Rao posted on LinkedIn earlier today a very interesting blurb, reporting on his use of this condition handling structure in conjunction with LLMs.

(Works for me in an incognito window, but you may not be able to see past the first comment if you don't have a LinkedIn account.)

The blurb references this more detailed account of the work, which I haven't been through in detail yet:

Gábor Melis introduces MGL-PAX, an "untangled" literate programming system for Common Lisp. An untangled system takes advantage from the flexibility of code order of a language to rely less on tangling tools.

@amoroso @aartaka Standardized #lisp #commonlisp has a bunch of different embedded languages (LOOP -> macro-based transpiler, FORMAT strings -> interpreter and transpiler, CLOS -> extension of Lisp, ...). As libraries there are zillions more of those. Then CL inherits features from Lisp 1, Maclisp variants and has evolved from CLtL1, CLtL2, ANSI CL. One thing that is missing: CL-USER . The CL-USER package contains an implementation specific largely extended version of Common Lisp.

@momo cool!

Well then, please have a listen to the episodes of the #LispyGopherClimate podcast that me, @kentpitman and @screwlisp did these past few weeks:

• Kent Pitman presents his lisp condition system implemented for python
• Kent Pitman, Scott Zimmermann, Ramin Honary, Screwlisp: Lisp Conditions in Python
• Common Lisp condition handling lore
• Common Lisp condition system, code review of my programming example
• Common Lisp condition handling w/ Kent Pitman, Ramin Honary

Artyom Bologov @aartaka describes the languages and programming styles that are in Common Lisp. To me Common Lisp is more a rich toolbox than a family of languages.

Daniel Kochmański @jackdaniel is revising the manual of McCLIM, starting from the chapters on the development history and getting started.

From this I learned that in 2026 it has been 10 years since he took over maintenance of McCLIM. Thanks to Daniel and all contributors for their work on this great implementation of the Common Lisp Interface Manager GUI toolkit.

This tutorial on building a GUI application in Common Lisp with GTK and SBCL is not new but has just crossed my feeds, so it's new to me.
