1. Does anybody know some reports about its realisation? 2. Immutable objects seem to be an ideal area to implement much more sophisticated storage allocation mechanisms than simple GC-algs: Consider two independently created sequences, structures or oneofs which are occasionally identical. The GC could remove one of them as one can be replaced with no effect by the others. This would be a very costly process indeed when one has to consider all existing objects. However, when one restricts this kind of "data compression" to some specific types the overhead would be locally limited. I am not shure if such a mechanism could be implemented in CLU itself, however has anybody considered this problem? Ulrich Neumerkel (ulrich@vip.UUCP UUCP: ...!mcvax!tuvie!vip!ulrich)
