# These test multi-regex searches with capture groups.

# NOTE: I wrote these tests in the course of developing a first class API for
# overlapping capturing group matches, but ultimately removed that API because
# the semantics for overlapping matches aren't totally clear. However, I've
# left the tests because I believe the semantics for these patterns are clear
# and because we can still test our "which patterns matched" APIs with them.
