    IO Class
    
+    
    The IO class can be used to read and write to and from the console.
    
+
    Static Methods #
    
+
    IO.print(objects...) #
    
+
    Prints any number of things to the console and then prints a newline
+character. If you don't pass it a string, it will be converted to a string for
+you. When passed multiple things, Wren outputs one after another.
    
+
    > IO.print("I like bananas")
+I like bananas
+> IO.print("Oranges", 10)
+Oranges10
+>
+
    
+
+
+
    IO.write(object) #
    
+
    Prints a single thing to the console, but does not print a newline character
+afterwards. If you pass it something that isn't a string, it will convert it to
+a string.
    
+
    > IO.write(4 + 5)
+9>
+
    
+
+
+
    In the above example, the result of 4 + 5 is printed, and then the prompt is
+printed on the same line because no newline character was printed afterwards.
    
+
    IO.read(prompt) #
    
+
    Reads in and returns a line of text from the console. Takes a single string to
+be used as a prompt. Pass an empty string for no prompt. Note that the returned
+line of text includes the newline character at the end.
    
+
    > var name = IO.read("Enter your name: ")
+Enter your name: John
+> IO.print("Hello " + name + "!")
+Hello John
+!
+>

    Semantically, values can be any object, and multiple keys may map to the
 same value. Keys have a few limitations. They must be one of the immutable
 built-in value types in Wren. That means a number, string,
 range, bool, or null. You can also use a class object as a
 key.
    
-
    The reason for this limitation—and the reason maps are called "hash tables" in other languages—is that each key is used to generate a numeric hash code. This lets a map locate the value associated with a key in constant time, even in very large maps. Since Wren only knows how to hash certain built-in types, only those can be used as keys.

    In addition, even though they aren't strictly immutable, fibers
