In perl, there are some pretty wild extensions to the regex syntax,
features that make it much more than a regular expression engine.
Yes, it is possible to match parentheses and other nested structures
(such as HTML), and the regex to do so isn't incredibly difficult.
Note that Python doesn't support this extension.
