I don't think we considered the possibility you might use do notation for the list monad, as it's not an idiom that seems to occur often.
depends where you look, I guess. (Such questions could in principle be answered automatically by browsing the code on hackage?) As I said, I am avoiding list comprehensions for purely optical reasons (putting the cart before the horse), so I write "do" in the list monad. Of course I prefer "let" to "where" for the same reasons, so for me you could indeed replace "guard" by "where", and "return" by "select", and "x <- foo" by "from x in foo" and it'd look like the real (linq) thing. - Oh, and replace "Monad" by "Workflow". - Not! NB: Wasn't there a time (before "do") when "list" notation (brackets) would work in any monad? And "map" was a method in "Functor",and we had "class Functor m => Monad m", etc. Well well well times have changed.
