Nice.  Glad to see that this is documented somewhere so I can start playing with
it.  One thing, though:  In my dstats library, I have a custom hash table
implementation that's used very heavily in my information theory module.  (I have
my reasons for using a custom hash table instead of the builtin, but they're
beyond the scope of this post.)  Right now, the hash table uses opApply.  Now that
I realize how horribly slow opApply is, I'd like to port this to ranges.  However,
I need to be able to iterate over either key, value pairs or just values.  Is
there any way to make this work with ranges?
