Add support for "nonlocal" (capitalized) names, and change how variable lookup works. Inside a method, all local variable lookup stops at the method boundary. In other words, methods, do not close over outer local variables. If a name is not found inside a method and is lowercase, it's a method on this. If it's capitalized, it's a global variable. 2015-01-13 21:36:42 -08:00			`var Nonlocal = "before"`
"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(Nonlocal) // expect: before`

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 {`
