Changes for version 0.043_03 - 2015-12-01
- Allow nesting of \Q with \U, \L, and \F The perlop docs say these nest with each other. Playing with Perl suggests that \U, \L and \F supersede each other, but thet they as a group nest with \Q in either order, so that if you specify \Q and one of the \U, \L, \F group you need two \Es to turn them all back off.
Changes for version 0.043_02 - 2015-11-28
- Restrict recognition of back references in replacement strings to \number form, since Perl itself does not recognize \g{...} or \k{...} there.
Changes for version 0.043_01 - 2015-11-25
- Recognize postfix dereference if desired. This is controlled by the Boolean argument 'postderef' passed to PPIx::Regexp->new(). The default is false, but will become true if postfix dereference becomes mainstream Perl 5. Add explain() and supporting methods main_structure() and in_regex_set(). The explain() method returns a brief explanation of what the element does.
