Yes, "8th" has late-binding, but only on-demand, using the word "`" (the
backtick).

The reason is that, say "+" may apply to a Number or a String (among
other things), and you may for example have an Array of one or the other
type.  So if you have a case where you don't know the type of item until
runtime, you can use the late-binding word.

Of course, that is going to be slower than interpret-time binding, but
if you need it, it is very handy to have.
