OK, but not having to explicitly "declare" variables is a feature that most people expect from dynamic languages, so you can hardly blame them for doing this all the time in shell. IMHO Python gets this global/local (implicit) declaration story right. Of course it is easier when you do not have 30 years of POSIX legacy to support (but just the experience). <http://docs.python.org/tutorial/controlflow.html#defining-functions>
