Clean up text handling a bit: - Rename IO.write -> IO.print. - Make IO.write not print a newline. - Support \u Unicode escapes in strings. 2014-01-05 12:27:12 -08:00			`while (c < 3) IO.print(c = c + 1)`

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			`a = a + 1`
