Summary: Represent an independent subexpression marker

Description:
The purpose of the _PPIx-Regexp_ package is to parse regular expressions in
a manner similar to the way the PPI package parses Perl. This class forms
the root of the parse tree, playing a role similar to PPI::Document.

This package shares with PPI the property of being round-trip safe. That
is,

my $expr = 's/ ( \d+ ) ( \D+ ) /$2$1/smxg';
my $re = PPIx::Regexp->new( $expr );
print $re->content() eq $expr ? "yes
" : "no
"
