That's not how I see it. Both 'use vars' and 'our' are used to keep "use strict 'vars'" happy, by declaring a global variable and allowing one to use it without specifying the full package name. The difference is that 'use vars' is not lexically scoped and affects the entire package, whereas 'our' takes the same scoping rules as 'my', but in contrast with 'my', refers to the same global variable. As far as I understand it, this has nothing to do with importing in the symbol table. -- felix -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
