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).
