PPIx::Regexp::Token::Whitespace - Represent whitespace
=head1 SYNOPSIS
use PPIx::Regexp::Dumper;
PPIx::Regexp::Dumper->new( 'qr{ foo }smx' )
->print();
=head1 INHERITANCE
C<PPIx::Regexp::Token::Whitespace> is a
L<PPIx::Regexp::NoOp|PPIx::Regexp::NoOp>.
C<PPIx::Regexp::Token::Whitespace> has no descendants.
=head1 DESCRIPTION
This class represents whitespace. It will appear inside the regular
expression only if the /x modifier is present, but it may also appear
between the type and the opening delimiter (e.g. C<qr {foo}>) or after
the regular expression in a bracketed substitution (e.g. C<s{foo}
{bar}>).
=head1 METHODS
This class provides no public methods beyond those provided by its
superclass.
