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")`
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			`Fiber.yield("yield 1")`

Allow passing a value when first starting a fiber. If the function the fiber is created from takes a parameter, the value passed to the first call() or transfer() gets bound to that parameter. Also, this now correctly handles fibers with functions that take parameters. It used to leave the stack in a busted state. Now, it's a runtime error to create a fiber with a function that takes any more than one parameter. 2017-10-19 20:45:13 -07:00			`// expect: yield 1`
