Create a bunch of test cases for unique boxes by copying box tests XFAIL the ones that don't work Issue #409 2011-09-23 16:58:06 -05:00

Switch to new param kind bound syntax And remove support for the old syntax 2012-01-05 08:35:37 -06:00			`fn test_generic<T: copy>(expected: ~T, eq: compare<T>) {`
Rewrite exhaustiveness checker Issue #352 Closes #1720 The old checker would happily accept things like 'alt x { @some(a) { a } }'. It now properly descends into patterns, checks exhaustiveness of booleans, and complains when number/string patterns aren't exhaustive. 2012-02-15 02:40:42 -06:00			`let actual: ~T = alt check true { true { expected } };`
