	After %b you put 2 characters, which indicate the start and end of the balanced pair. If it finds a nested version it keeps processing until we are back at the top level. In this case the matching string was "(big fish (swimming) in the pond)".		After %b you put 2 characters, which indicate the start and end of the balanced pair.

		+	Especially if you're used to other languages with regular expressions, you might expect to be able to do stuff like this:
		+
		+	'(foo)+' -- match the string "foo" repeated one or more times
		+	'(foo\|bar)' -- match either the string "foo" or the string "bar"
