    # We have to create and test Perl::Critic::Document for memory leaks
    # separately because it is not a persistent attribute of the Perl::Critic
    # object.  The current API requires us to create the P::C::Document from
    # 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.
