Variable dependencies start to matter a lot when you=E2=80=99re trying to refactor code =E2=80=94 e.g. to extract part of a function into a new funct= ion of its own. In this case, variables shared by the code that stays and the code that moves out are a source of complexity, and their number may be a factor in deciding which refactoring the code actually wants.
