Sounds reasonable to me.
I don't have any particular input on the module names or hierarchy.
Cheers,

I'd like containers to export more Data.Sequence internals, and to do so in a way that allows external users to rely on them. I propose the following:
1. Add a module, Data.FingerTree.IntPlus, abstractly exporting the finger trees used to represent sequences. These can also be used for other finger trees with measurements in the (Int, +) monoid. This would include various basic operations for cons, snoc, and splitting, with most names the same as for sequences. 2. Add a module, Data.FingerTree.IntPlus.Unsafe, exporting efficient mapping/traversing functions that rely on specific preconditions to maintain the internal fingertree annotation invariant. 3. Add a module, Data.Sequence.StableInternal, exporting the internal structure of sequences and also some internal functions that may be useful elsewhere (I'm particularly interested in the `splitMap` function and future variants thereof). Unlike the `.Internal` module, this module would be subject to the package version policy, and would therefore be more suitable for use by other packages.
I am very open to suggestions for modifications to the module names. One option might be to put all the FingerTree.IntPlus stuff in the Data.Sequence.StableInternal hierarchy, if folks think it should be buried a bit.
