What's wrong with us? Are we some kind of rebel cult going against the flow of

Well, globals aren't _inherently_ evil; it is how they are used (as in is their
use justified and proper) that determines that. GOTO has acquired the same
reputation, although, carefully and cleverly used, it is justified.

In some languages globalization is assumed and local variables must be
specifically declared as such. In others, including Ruby, localization is
assumed and global variables must specifically be declared as such. Instance
variables are a special hybrid -- local at the class level but 'global' within
the class (i.e. visible to all methods)
