This suggests that your monad will work less efficiently if you use it with
the do-notation.

Join and bind are very similar and, at least in standard Haskell code, I
think that "bind" has proven to be a lot more useful then "join".

Also, as I mentioned before, if people find "join" easier to define then
"bind", then they can define "join", and then define "bind" in terms of
that---I am still not convinced that we need a new method added to the Monad
class.
