Convert all fns to block arg syntax. 2014-04-02 19:41:53 -07:00			`var f = new Fn {`
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			`IO.print("evaluate sequence")`
For loops! 2013-12-24 21:04:11 -08:00			`return [1, 2, 3]`
			`}`

Allow empty argument list methods. - Compile them as calls and definitions. - Use them for call(), clear(), run(), try(), and yield(). - Update the docs. 2015-02-26 23:08:36 -08:00			`for (i in f.call()) IO.print(i)`
For loops! 2013-12-24 21:04:11 -08:00			`// expect: evaluate sequence`
