"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			`for (i in [1]) System.print(i)`

Move newline handling down into parser. This lets us make it a grammar feature and not a lexer trick. Newlines are explicitly ignored in some parts of the grammar. This lets, for example, things like "\|" ignore the newline when used as an operator, but not when used as a parameter delimiter in a block argument. 2014-04-04 07:51:18 -07:00			`for (i in [1]) {`
