# We put these tests here because they are written primarily against the
# regex-automata API, and in particular use regex-automata features for
# conditional compilation. If we moved these up as tests on 'regex' proper,
# then we'd need to duplicate regex-automata's complex features on 'regex' too,
# which I really do not want to do.
