Does it really use global variables (err, variables in the main package; I assume it doesn't use the truly global punctuation variables, other than for their intended uses), or does it use package variables in its own package?

Call them package variables if you want to -- they still meet the definition of "global variable" in most languages, i.e. they are read/write accessible by any code from anywhere. I'm not going to go into a whole explanation of why using globals to pass information, regardless of the use of OO or not, is a really bad design, because many other people have written about it at length. It's not as if these globals are being used internally only -- they are part of the public API for File::Find.
