I think, we need a general solution for freeze, dump and clone. As shown the latter is broken. That would be IMHO an iterator interface with a callback function taking and returning a void*. (The dump could be done from the frozen string too, but you might not always have all flags and such for just printing a PMC during tracing, so a special dump() vtable is more flexible - the PMCs should decide how they look like) > I thought we had a freeze and thaw entry in the vtables, but I see not. > The signatures (since I don't have source handy to check them in) should > be: > STRING *freeze() The freeze(), dump() and clone() would be vtables which are called by the iterator.
