regex: grouping missing from the curriculum
See original GitHub issueWe teach something obscure as lookahead, but not the more often used grouping for the sake of subexpression choice, eg. a(bc|def)g.
Grouping is indirectly taught for capture groups and lookahead, but plays the same general role in both, capturing or not. So this lesson would fit nicely before that, after character groups.

Oh, if I wasn’t clear: I believe an extra lesson is in order, right after the OR one. Maybe something like “find all the words that have ‘foo’ or ‘bar’ in them”, just long enough to avoid character-list hacks.
Knock yourself out. 😃
