Make block results work for generic types I think just about every type can be used as a block result now. There's quite a proliferation of tests here, but they all test slightly different things and some are split out to remain XFAILed. The tests of generic vectors are still XFAILed because generic aliased boxes still don't work in general. 2011-04-05 23:42:33 -04:00
Reformat source tree (minus a couple tests that are still grumpy). 2011-06-15 11:19:50 -07:00

Switch to new param kind bound syntax And remove support for the old syntax 2012-01-05 15:35:37 +01:00			`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 09:40:42 +01:00			`let actual: T = alt check true { true { expected } };`
