I have a handful of projects.  The tiny ones are one-source, the biggest one (dbf) is not.

If I had an entire application I would probably split the difference, and just have dual source on a single module to
hold the classes/functions that absolutely-had-to-have-this-or-that-feature (exec (the statement) vs exec (the function)
comes to mind).
