Are punctuation variables truly global or are they forced to be in main:: when unqualified?

    They are forced into main::, but they are global. You can abuse this by starting your string with a control character: ${^Foo} is also forced into main::. (it's actually ${"\cFoo"})

[MidLifeXis]: And it also has the 0.14 version of the tarball in its manifest.

[MidLifeXis]: Although the previous one could be a b0rken PATH, I would need to dig for that.
