http://www.mail-archive.com/haskell-cafe@haskell.org/msg15656.html Will Data.Map with its' empty, insert, findMin, etc, "methods" conform to your proposed type? but Data.Map isn't sequential container. instead, it maps arbitrary keys to values
That situation reminds me situation with Set Monad instance. ;) Basically, you - and others, - propose to add another class isomorphic to already present lists. I think, most benefits of that class can be achieved by using list conversion and RULE pragma.
