Yes, these are issues that should be addressed by layers on top of
what I have so far.  I could even see this being integrated into an
IDE.  The split-in-two operation sounds very useful.  As does
mega-split warning.  Moving a single symbol, or a list of symbols,
sounds like another great option.  I realized that split was not going
to be the final solution, but it had a very simple signature and led
to the implementation of all the mechanisms these nicer operations
will require.
