You can add this yourself. See perlre at the end.

package Regexp::Quotes;
use overload;

sub import {
    shift;
    die "No argument allowed to Regexp::Quotes::import" if @_;
    overload::constant qr => \ &convert;
}

sub invalid {
    die "/$_[0]/: invalid escape '\\$_[1]'";
}

my %rules = (
    '\\' => "\\",
    'q' => qr/[\'\" .... ]/ ); # Extend this

sub convert {
    my $re = shift;
    $re =~ s( \\ ( \\ | q ) )
            { $rules{$1} or invalid( $re, $1 ) }gex;
    $re;
}
