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
