Thanks, Gwern. So your line of interest is similar to mine. :) I have one question: the page you referred to says "live hacking [in stumpwm] means you can hose your X session" It's correct, and I have done it several times in Sawfish, like infinite loops. (I've never tried StumpWM.) But isn't it the same for any of these WMs that if you have errors in your code, your WM can be almost unusable, no? Or is it less likely in haskell? It's better to byte-compile in Lisp, too. Sawfish's lisp (librep) is poor, but I guess common lisp compiler may be able to emit good warnings. (And please make it habit to record the date of last web page edit, which is really informative for readers.) I don't understand why large desktop is not so much common (famous example which has LD is fvwm); it's really convenient since geometric meaning is intuitive. For example, my top-right viewport (a viewport is the portion shown in a monitor) is assigned for browser, and I switch the viewport by Shift + cursor. I only have one workspace, but some Sawfish user have several large workspaces. # Wow, you're interested in 柄井川柳 (Karai Senryu)? I don't know # about him at all, but I'm interested in Edo period senryu, too. # I'm Japanese. :) Teika (Teika kazura, retired Sawfish developer)
