There are a handful of global variables -- punctuation ones, mostly.

Wouldn't that make it lexical? Good question.
The answer is no, because lexical variables expire once they are outside a certain scope, and cannot be referenced outside of that scope.
Global package variables on the other hand, can be accessed at any time, as long as you use the package names and colons preceeding the variable name.
Hope that clears up a few things... | [reply] |
