In Perl, a regular expression match is written with 'm',
followed by a delimiter, then the pattern, then another
delimiter. The delimiter can be pretty much any non-word, no-
whitespace character, and brackets ([{<>}]) can be paired with
their opposites. If slashes are used as the delimiter, the 'm'
can be omitted, so slashes are normally used unless there are
slashes in the pattern itself, in which case another delimiter
is often used to avoid the need to backslash the slashes in the
pattern. For more, see the Perl documentation:
