I think the code is more readable this way. The very fact that the
switch branches are completely independent is good enough reason to make
them distinct functions, IMHO. Breaking 900 lines of code into smaller
chunks of code, each of which does a single conceptual task, just makes
the whole enterprise easier to understand. As for sharing code between
the functions, I agree that isn't done today -- but it will be easier to
do in the future with this refactoring.
