PPI::Normal has the intention, in the long run, of normalizing Perl in such a way that functionally equivalent code will present the same DOM tree. Originally PPI::Normal was close to that, but further development of PPI has scaled it back somewhat.

As for your question about B::Deparse, currently I'm using it like this:

my $deparse = B::Deparse->new(
    "-p",   # add extra parentheses
    "-q",   # expand double-quoted strings
    "-sC",  # cuddle else/elsif/continue blocks
    "-x3",  # expand syntax constructs
);

Unfortunately, that doesn't handle the case of variables having different names, even if the code is functionally equivalent. Your LISP solution sounds interesting but I wonder how I would present the got/expected failure information? Not too many people are going to want to look at at a LISP equivalent.
