I want to print out a large ELisp data structure prettily. The Gnus newsrc.eld, for example, or the Gnus registry hashtable. I'll use whatever makes it happen as fast as possible.

With my list-print-separator patch you get fast and OK-looking. Are you concerned it's only useful sometimes? The speed penalty is minor if it's not used. Perhaps people will use it more if it's available. Maybe it could be a function too, to be called with the print-level, so the indentation can vary and so on. But for my purposes it's enough to have just a string. Ted
