I don't know anything about indexed monads, but it seems that you can use
the 'where' keyword to rebind (>>) and return for any block you want [1].
An example from [1]:
addNumbers = do
80
60
10
where (>>) = (+)
It might be possible to generate this where block using TH.
There is also a quasi-quoter available for indexed-do-notation [2].

I have a program that uses both monads and indexed monads, and I'd like to use do-notation for each in the same source file. Is there a way to rebind syntax for only the do blocks that make use of an indexed monad?
Thanks, Mark
