Port the tests to the decl foo<T> syntax. 2011-08-12 08:37:25 -05:00			`fn swap<@T>(v: &[mutable T], i: int, j: int) { v.(i) <-> v.(j); }`
Write some tests for swap. 2011-06-15 19:08:10 -05:00

Convert most working tests to ivecs I tried to pay attention to what was actually being tested so, e.g. when I test was just using a vec as a boxed thing, I converted to boxed ints, etc. Haven't converted the macro tests yet. Not sure what to do there. 2011-08-12 17:42:39 -05:00			`let a: [mutable int] = ~[mutable 0, 1, 2, 3, 4, 5, 6];`
