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			`var fiber = Fiber.new {`
"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			`System.print("fiber 1")`
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			`Fiber.yield()`

Fibers! Still have some edge cases to implement but the basics are in place and working now. 2014-01-12 11:02:07 -08:00
Revise low level fiber semantics to play nicer with schedulers. Now that I'm starting to write a real async scheduler on top of Wren's basic fiber API, I have a better feel for what it needs. It turns out run() is not it. - Remove run() methods. - Add transfer() which leaves the caller of the invoked fiber alone. - Add suspend() to return control to the host application. - Add Timer.schedule() to start a new independently scheduled fiber. - Change Timer.sleep() so that it only transfers control to explicitly scheduled fibers, not any one. 2015-08-30 22:15:37 -07:00			`fiber.call() // expect: fiber 1`
