Hello everyone, we've managed to set me up as co-maintainer for cl-prevalence. I intend to release the next version soon; it will be mostly a bugfix/cleanup release*. All changes made so far are here: http://bitbucket.org/skypher/cl-prevalence/ Anton, I've merged your CLISP changes. I can't merge Tomas Zellerin's PROBE-DIRECTORY fixes because I don't have write access to S-SYSDEPS. If someone would prepare a patch purely for cl-prevalence I'd likely commit it. Are there still CLISP people reading this? If yes then please test whether the version above works for you (excluding multi-processing). Tests from people using other implementations would be nice too. Cheers, Leslie * the larger fix for correct object references and identity will be part of a later release. -- http://www.linkedin.com/in/polzer
