What is the layer stack? That term doesn't seem to be defined anywhere. (OK, I can make a guess based on what perl 5.8 is doing) I can see why one would have a layer stack on an open file handle, but doesn't open crate file handles? Or is the action of "open" something that happens after file handle construction (hence there can be a stack by open time)? Nicholas Clark
