The method of grouping regex lookarounds together logically is by using parentheses. This creates a separate group within the regex pattern, allowing the lookarounds to be applied only to the contents within the group. For example, the regex pattern "(?=foo)(\d+)(?<=bar)" groups the lookahead assertions (?=foo) and (?<=bar) together, and applies them to the contents (\d+) within the group. This will match any digit (\d+) that is surrounded by the strings "foo" and "bar", without including "foo" and "bar" in the match itself.
