# an instance of an existing PPI::Document. In the future, I hope to make
# that interface a little more opaque. But this works for now.
# Coincidentally, I've discovered that PPI::Documents may or may not
# contain circular references, depending on the input code. On some
# level, I'm sure this makes perfect sense, but I haven't stopped to think
# about it. The particular input we use here does not seem to create
# circular references.
