Start getting block scope working. 2013-11-18 09:19:03 -08:00			`// Body has its own scope.`

Get closures working! In the process, I had to change the grammar. There is now a strong separation between statements and expressions. The code was just wrong before when it popped locals at the end of a block scope because there could be temporaries on the stack if the block was in expression position. This fixes that. Still need to implement closing over `this`. 2013-12-04 07:43:50 -08:00			`while ((i = i + 1) <= 1) {`

			`}`
Make IO a static class instead of a singleton. 2013-12-21 19:25:09 -08:00			`IO.write(a) // expect: outer`
