+
+#### type Token
+
+```go
+type Token int
+```
+
+Token is the set of lexical tokens in JavaScript (ECMA5).
+
+#### func  IsKeyword
+
+```go
+func IsKeyword(literal string) (Token, bool)
+```
+IsKeyword returns the keyword token if literal is a keyword, a KEYWORD token if
+the literal is a future keyword (const, let, class, super, ...), or 0 if the
+literal is not a keyword.
+
+If the literal is a keyword, IsKeyword returns a second value indicating if the
+literal is considered a future keyword in strict-mode only.
+
+7.6.1.2 Future Reserved Words:
+
+    const
+    class
+    enum
+    export
+    extends
+    import
+    super
+
+7.6.1.2 Future Reserved Words (strict):
+
+    implements
+    interface
+    let
+    package
+    private
+    protected
+    public
+    static
+
+#### func (Token) String
+
+```go
+func (tkn Token) String() string
+```
+String returns the string corresponding to the token. For operators, delimiters,
+and keywords the string is the actual token string (e.g., for the token PLUS,
+the String() is "+"). For all other tokens the string corresponds to the token
+name (e.g. for the token IDENTIFIER, the string is "IDENTIFIER").
