Tests for explicit exception chaining This also breaks out the PY3 only tests into their own file. We need to do this because raise from is a syntax error in PY2, so we can't rely on the previous hack of catching a HyCompileError - it would compile fine through Hy and then be a syntax error in Python. 2014-05-01 16:31:45 -04:00			`;; Tests where the emited code relies on Python 3.`

revert yield-from test Yield-from was introduced in 3.3, so we have to catch the compile error that's raise in 3.2. :( 2014-06-09 16:33:32 -04:00			`(import [hy._compat [PY33]])`
