Hi David, Thanks ... I just looked at CLJOS, and was actually just earlier thinking about writing something similar myself. It looks very nice, and I very well might end up using it (especially if it gets up-to- speed with "struct"). Still, I stand by my feature request :).
I guess in the mean-time I could use symbols instead of keywords for my class types. However, I assume that would slow things down substantially (unless method caching would take care of this; I'll have to check on that.) -Jason On Jan 19, 7:49 pm, David Nolen <dnolen.li...@gmail.com> wrote: > My OO example from earlier deals with this case by completely removing any > need to manually derive tags.
