Matching strings

In the previous section you wrote patterns and tested them with the smartmatch operator ~~. This section looks more closely at what that operator gives you back: a match object that carries all the information about what was found and where.

You will also see the different ways of writing a regex, and how to ask the simple yes-or-no question “did the string match at all?”.
