Error parsing text/turtle

[Stephan Tittel]

Hi, thanks for your great library. Recently I encountered an error parsing turtle with booleans in it. Here is an example to reproduce:

package main

import (
  "fmt"
  "strings"
  "github.com/deiu/rdf2go"
)

func main() {
  g := rdf2go.NewGraph("")
  if err := g.Parse(strings.NewReader(`<s> <p> [ <o> true; <other> <triple> ] .`), "text/turtle"); err != nil {
    panic(err)
  }
  fmt.Println(g)
}

This results in:

panic: Expected object, got Expected ':' while lexing pname%!(EXTRA []interface {}=[]) (type %!s(easylex.TokenType=-2))
