This is not a fully baked idea, perhaps there's a good reason we haven't
added a binary `~`. It seems like I've seen discussion in the past. But
I couldn't find such discussion. And as I'm currently taking some
statistics courses, I'm getting R-feature-envy again...
Sorry, but I did not understand what this operator does, except that it
has some relation to R.
For the "-" operators, unary and binary operators are related. For an
number x
-x == 0 - x
Is there similar relation between unary and binary "~"?
~x == 0 ~ x
I guess "~" is a bitwise NOR operator (or Peirce's arrow):
x ~ y == ~x & ~y
