My personal take on why nobody uses it is that when you have a large
library of data structures, all of which support various interfaces,
the problem arises as to how you pick which one to use.

Without looking, what is the difference between a BraunSeq and a
BankersQueue?

I've also found it hard to merge data structures which are embedded
in a monad with data structures which are not.  Getting a consistent
interface there is hard.

If you can think of a solution to either or both of these problems...
