Pickled tags don't == tags from parsed filenames with same str() representation?

I tried pickling some tags and evaluating them in a different interpreter, and tag1 != tag2 even though str(tag1) == str(tag2). Is this intentional?

Do you think the __eq__
function needs an update?

No, I think the PR linked above #860 has the correct solution.
