Our parser extends [RegexParsers](https://javadoc.io/static/org.scala-lang.modules/scala-parser-combinators_2.13/2.0.0/scala/util/parsing/combinator/RegexParsers.html) because we do some lexical analysis. `"""[a-z]+""".r` is the regular expression. `^^` is [documented](https://javadoc.io/static/org.scala-lang.modules/scala-parser-combinators_2.13/2.0.0/scala/util/parsing/combinator/Parsers$Parser.html#^^[U](f:T=>U):Parsers.this.Parser[U]) to be "a parser combinator for function application". Basically, if the parsing on the left of the `^^` succeeds, the function on the right is executed. If you've done yacc parsing, the left hand side of the ^^ corresponds to the grammar rule and the right hand side corresponds to the code generated by the rule. Since the method "word" returns a Parser of type String, the function on the right of `^^` needs to return a String.

 So how do we use this parser? Well, if we want to extract a word from string, we can call
