I realize this is tongue-in-cheek, but & is not universally the "bit-wise and"
operator.  In the POSIX shell saying "foo & bar" means to start processing foo
asynchronously and then run "bar".  But that also breaks the piping analogy
lens is using & for, so hmm...

I think |>= and |>~ would just be unfortunate, and lens is likely to be one of
the biggest users of this new operator (at least at this point in time).
