The slashes are delimiters of a constant regular expression, like quotes are delimiters for a constant string. They are not part of the regular expression or the string.
Without the delimiters too many characters would conflict with the syntax.
Delimiters are not needed for variables - and indeed not allowed.

ppix::regexp::structure::main
PPIx::Regexp::Structure::Main(3pm) User Contributed Perl Documentation PPIx::Regexp::Structure::Main(3pm)
NAME
PPIx::Regexp::Structure::Main - Represent a regular expression proper, or a substitution
SYNOPSIS
use PPIx::Regexp::Dumper;
PPIx::Regexp::Dumper->new( 'qr{foo}smx' )
->print();
INHERITANCE
"PPIx::Regexp::Structure::Main" is a PPIx::Regexp::Structure.
"PPIx::Regexp::Structure::Main" is the parent of PPIx::Regexp::Structure::Regexp and PPIx::Regexp::Structure::Replacement.
DESCRIPTION
This abstract class represents one of the top-level structures in the expression. Both PPIx::Regexp::Structure::Regexp and
PPIx::Regexp::Structure::Replacement are derived from it.
METHODS
This class provides the following public methods. Methods not documented here are private, and unsupported in the sense that the author
reserves the right to change or remove them without notice.
delimiters
This method returns a string representing the delimiters of a regular expression or substitution string. In the case of something like
"s/foo/bar/", it will return '//' for both the regular expression and the replacement.
interpolates
This method returns true if the regular expression or replacement interpolates, and false otherwise. All it really does is to check whether
the ending delimiter is a single quote.
SUPPORT
Support is by the author. Please file bug reports at <http://rt.cpan.org>, or in electronic mail to the author.
