Oh, and note that you can pass R'd reductions as if they were normal prefix
ops:
$ perl6 -e 'sub dueet(&op, *@list) { op @list }; say dueet &prefix:<[R-]>,
1..100'

In general, it's kind of pointless with bare infix ops, as you can just
reverse the arguments, but when reducing or the like, it becomes much more
valuable.

I've just stumbled across "reversed operators", e.g. say 4 R/ 12; # 3
in the documentation. I'm curious to know why the language includes
them? I'm having trouble understanding where they would be useful.
