Hi all, I've implemented support for keyword arguments (corresponding to define* and lambda*) in GOOPS. The functionality is similar to that of CLOS (which also has keyword in methods) in that dispatch is not done on the keyword part. You can find the changes in the goops-keyword branch at https://github.com/mdjurfeldt/guile/tree/goops-keyword or in the included patch. Comments? Best regards, MIkael
