The following conventions are used in the examples.<ref name="clarify000">The character 'm' is not always required to specify a perl match operation. For example, m/[^abc]/ could also be rendered as /[^abc]/. The 'm' is only necessary if the user wishes to specify a match operation without using a forward-slash as the regex [[delimiter]]. Sometimes it is useful to specify an alternate regex delimiter in order to avoid "[[Delimiter#Delimiter_collision|delimiter collision]]". See '[http://perldoc.perl.org/perlre.html perldoc perlre]' for more details.</ref>
