Tweak Sequence.all() and Sequence.any(). When possible, they return the actual value from the predicate instead of always just "true" and "false". This matches && and \|\| which evaluate to the RHS or LHS when appropriate. 2015-03-28 10:18:45 -07:00			`var a = [1, 2, 3]`
"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(a.any {\|x\| x > 3 }) // expect: false`
