#### 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.

#### 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").
