Revision history for Perl extension PPI

1.109    Fri Dec 30 2005
	- Various bug fixes
	- Minor structural cleanup

	- Removed every single use of UNIVERSAL::isa
	- PPI::Normal was quite broken, cleaned it up
	- Fixed PPI::Normal::Standard::remove_statement_seperator
	- Fixed CPAN #16674 PPI::Token::Quote::Double->interpolations
	- Fixed CPAN #15131 PPI::Node->find() behavior not completely
	  documented (Jeffrey Thalhammer)
	- Fixed CPAN 13743 PPI::Statement::Scheduled api (johanl)
	- PPI::Statement::Scheduled is now a subclass of PPI::Statement::Sub
	- Removed breaking circular include in PPI::Util
	- Removed an 'our' variable in t/04_element.t that created a 5.6.0 dependency
	- Only do the PPI::Cache tests that use Test::SubCalls if >= 5.006
	- (Except for File::Remove, we should ACTUALLY depend on 5.005 now)
	- Fixed CPAN #16671 $_ is not localized (JPIERCE)
	  (I missed an unlocaled $_ hiding in the Node object destructor)

1.108    Thu Dec 15 2005
	- Fixing of some very minor bugs

	- 8 wasn't an illegal character in an octal number (fixed)
	- Two <<heredocs with no content on the final line didn't round-trip (fixed)

1.107    Wed Dec 14 2005
	- PPI is now Editor-compatible.
	- You can create a PPI::Document from random ASCII line noise!

	- Added a dozen various patches to complete round-trip Tokenizer
	  and Lexer support for absolutely anything (i.e. line noise)
	  inside the normal set of ASCII characters used in Perl programs.
	- Does not include Latin-1 and Unicode line noise (yet).
	- Completely the 21_exhaustive.t test script.
	- Tested 21_exhaustive.t against 500,000 x 120-character
	  completely random line noise Perl programs.
	  (Apparently I'm still leaking 1k per document somewhere)

1.106    Sun Dec 11 2005
	- More changes to support all possible 4-character programs

	- Various fixes to weird things like *::'

1.105    Sat Dec 10 2005
	- Improvements driven by Audrey Tang's pugs wishlist.
	  (So pugs can parse Perl 5, eep)
	- Latin-1/Unicode improvements (but now requires perl >= 5.8.5)
	  (not pre-checked and enforced yet, but will be)
	- Starting new generation of "exhaustive" testing

	- Added 20_tokenizer_regressions, which tests all
	  detectably-failing 3-or-less character long Perl programs
	  (not inclusive of latin-1 or Unicode). (Audrey Tang)
	- Fixed bug for incomplete <READLINE> quotes at EOF
	  (there may be a few more similar cases)
	- Fixed bug with $'0 (where 0 is only legal after ::)
	- No longer die for illegal chars in hex/bin number types
	  (Attach the error to $token->{_warning} instead)
	- Caught a number of cases with trailing colons for $things
	  (Both at EOF and end of token)
	- Convert [^\W\d]\w* to (?!\d)\w+ to improve unicode support
	  in symbols etc (Audrey Tang)
	- Miscellaneous doc bugs in the SYNOPSIS (Audrey Tang)

1.104    Thu Nov 10 2005
	- No change to code
	- Both List::Util and List::MoreUtil contain memory leaks,
	  and we use them extensively. Pushed the dependencies up
	  to versions with the memory leaks fixed.

1.103    Thu Oct  6 2005
	- Small bug fix that shouldn't have escaped

	- Changed md5hex_file to act more like the PPI::Documeny way.
	  That is, localise and THEN convert to \015

1.102    Wed Oct  5 2005
	- Small things to support Perl::Metrics

	- Added undocumented PPI::Util::md5hex_file function

1.101    Thu Sep 29 2005
	- Bug fix release

	- Fixed CPAN bug #14436 and #14440, misparse for my ($foo) ...
	- Added an self-analysis test script for PPI-testable problems
	- Fixed some minor bugs it threw up.

	- Major bug fixing
	- Some additions to help simplify Perl::Metrics

	- A whole bunch (practically all) of the sibling code was breaking
	  under non-trivial use. Fixed, with a number of new tests added.
	- Added function PPI::Util::md5hex
	- Added method PPI::Document::hex_id

	- Various bug fixes
	- Completed the first version of PPI::Cache

	- Expanded round-trip testing coverage to all the lexer and
	  regression test files
	- 06_round_trip.t wasn't doing the round-trip test properly.
	  Fortunately, this only resulted in false failures, so no
	  actual damage was done as a result of this.

	- Added PPI::Cache class
	- Removed warning in 99_pod.t

	- Added native Storable support

	- Removed dependency on Class::Inspector

0.996 Fri Jul  8 2005
	- Clearing all remaining RT bugs

	- Changes separated into General and Details from here on
	- Complete re-organisation of the quote-like token classes.
	  Any and all code that works with quotes will be broken.
	- Gave up on the old PPI::Query code and wrote a complete new and
	  much thinner implementation based roughly on the API of
	  PPI::Find uses the &wanted function (which also has a slightly
