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.

## Methods
|
|
|
|
### **name**
|
|
|
|
The name of the class.
|
|
|
|
### **supertype**
|
|
|
|
The superclass of this class.
|
|
|
|
:::dart
|
|
class Crustacean {}
|
|
class Crab is Crustacean {}
|
|
|
|
System.print(Crab.supertype) // "Crustacean".
|
|
|
|
A class with no explicit superclass implicitly inherits Object:
|
|
|
|
:::dart
|
|
System.print(Crustacean.supertype) // "Object".
|
|
|
|
Object forms the root of the class hierarchy and has no supertype:
|
|
|
|
:::dart
|
|
System.print(Object.supertype) // "null".
