I've had some success at using Scion within my config [1]. To use it, you'll need to move Data.Rope and Data.Prototype into the exported modules for the yi library in yi.cabal, and install the scion library from scion/lib/ in the the GitHub repository.
Once it compiles, just run ":scion" within a function definition. Most files within Yi won't work, because it has trouble with Paths_yi (and monads-fd vs. mtl), but Yi/String.hs does; try placing the cursor in the 'fillText' definition (the type definition line won't work), and it should print the type in the status line. It's pretty complicated right now, but the capability is defiitely there.
