"IO" -> "System". Get rid of the separate opt-in IO class and replace it with a core System class. - Remove wren_io.c, wren_io.h, and io.wren. - Remove the flags that disable it. - Remove the overloads for print() with different arity. (It was an experiment, but I don't think it's that useful.) - Remove IO.read(). That will reappear using libuv in the CLI at some point. - Remove IO.time. Doesn't seem to have been used. - Update all of the tests, docs, etc. I'm sorry for all the breakage this causes, but I think "System" is a better name for this class (it makes it natural to add things like "System.gc()") and frees up "IO" for referring to the CLI's IO module. 2015-09-15 07:46:09 -07:00			`Fn.new { System.print("ok") }.call() // expect: ok`

Make constructors just methods. * Eliminate "new" reserved word. * Allow "this" before a method definition to define a constructor. * Only create a default constructor for classes that don't define one. 2015-07-10 09:18:22 -07:00			`Fn.new {`

Unify body handling. Blocks, functions, and methods now have the same code for handling their bodies. This means that single-line methods work like single-line functions: they return the result of their expression. 2014-04-03 07:48:19 -07:00			`// Multiple statements.`
