-- These test cases compile two or more modules at a time.
-- Any file prefixed with "other" is compiled.
--
-- Note that these are run in three compilation modes: regular,
-- multi-file and separate. See the docstrings of
-- mypyc.test.test_run.TestRunMultiFile and
-- mypyc.test.test_run.TestRunSeparate for more information.
--
-- Some of these files perform multiple incremental runs. See
-- test-data/unit/check-incremental.test for more information
-- about how this is specified (e.g. .2 file name suffixes).
