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 22:42:33 -05:00
Reformat source tree (minus a couple tests that are still grumpy). 2011-06-15 13:19:50 -05:00

Make fn denote a bare function. Convert fn to fn@ as needed 2011-10-18 17:07:40 -05:00			`type compare<T> = fn@(T, T) -> bool;`

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>) {`
Reformat for new syntax 2011-07-27 07:19:39 -05:00			`let actual: T = { expected };`

Add pass-by-ref annotation to the tests to make them typecheck Issue #1008 2011-10-06 05:50:24 -05:00			`fn compare_vec(&&v1: @int, &&v2: @int) -> bool { ret v1 == v2; }`
make bind syntax unnecessary: just use _ for one of the arguments 2012-02-07 08:37:08 -06:00			`let eq = compare_vec(_, _);`
Port the tests to the expr foo::<T> syntax. 2011-08-13 02:10:18 -05:00			`test_generic::<@int>(@1, eq);`
