Adam Kennedy's new module PPI:
http://www.perl.com/pub/a/2005/06/09/ppi.html
http://search.cpan.org/perldoc?PPI
His module attempts to implement a parser that:
... creates a "round-trip" capability, parsing a file into an internal
model and back out again without moving a single white space character
out of place. Even if parts of a file are broken or badly formatted,
you can still change other parts of the file and save it correctly
without it changing anything you don't alter.
Second, it makes the parser extremely safe and error-tolerant. Any
code open in an editor is there for a reason--generally because it
isn't finished yet, is broken, or needs changing. A document parser
can hit a problem, flag it, stumble for a character or so until it
finds something it recognizes, and then continue on.
I wonder if there are concepts in his implementation that have a
bearing on Perl 6 design?
