7.1.1 Regular Expressions as Patterns
-------------------------------------
Regular expressions are one of the first kinds of patterns presented in
this book. This kind of pattern is simply a regexp constant in the
pattern part of a rule. Its meaning is `$0 ~ /PATTERN/'. The pattern
matches when the input record matches the regexp. For example:
/foo|bar|baz/ { buzzwords++ }
END { print buzzwords, "buzzwords seen" }
