var list = [1, 2, 3, 4, "foo"]

System.print(list.contains(2))      // expect: true
System.print(list.contains(5))      // expect: false
System.print(list.contains("foo"))  // expect: true
System.print(list.contains("bar"))  // expect: false
Moved List.contains to Sequence.contains, added tests and docs 2015-03-15 15:43:10 +01:00			`var list = [1, 2, 3, 4, "foo"]`

"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(list.contains(2)) // expect: true`
