Adam Kennedy's new module 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?
