    Only standalone graphemes and non-characters allowed as delimiters
    starting with Perl 5.29.0.
    
    Non-ASCII delimiters started working in 5.8.3, so that is what
    perl_version_introduced() returns for them.

    Collateral with all this, accept word characters as delimiters, but
    only with at least one space between the operator and the expression
    -- that is, 'qq xyx' is OK, but 'qqxyx' is not.

  Fix problem handling nested brackets.

  Fix various corner cases, including such things as '${^O}', '${]}',
    and even '$${$_[0]}', which turned out to be '$$' followed by
    '$_[0]'.

  Also pulled the variable recognition out into a separate module in
    anticipation of it being used other places.

  Dumper message if arg does not parse

  Recognize "$^O" (e.g.) as interpolating $^O, not $^ followed by a
    literal "O".

  Require PPI, which was formerly optional. This is because I decided
    that the variables() method (which needs it) was one of the
    fundamental points of the module.

  Another attempt to make old Perls work. Version 0.002 assumed I could
    have other interpolations in a regex with (??{...}), but this turned
    out not to be the case if Perl was earlier than 5.18.0. This was
    actually a step in the wrong direction since (?-1) works back to
    5.10.0.

  Add PPIx::QuoteLike::Dumper, redo eg/pqldump to use it.

  Recognize postderef slice syntax. This is stuff like $x->@[0,2] (array
    slice) or $x->@{foo,bar} (hash slice).

  Add methods perl_version_introduced() and perl_version_removed(). As
    of this release, the former returns '5.000' unless '\F' or postfix
    dereferencing are detected, and the latter always returns undef.

  Eliminte blockers to running under Perl 5.6. The significant change
    was replacing (?-1) in a regular expression (introduced in 5.9.5)
    with (??{...}) (going back to Heaven knows when, and used in
    Regexp::Common back in 2003).

  Initial release to CPAN.
