    I tried for Groovy 1.7.3(GroovyConsole) and have following:

    class Name {
    String id = "Sargis"
    }

    def name = new Name()
    println name.id
    println name.getId()
    println name['id']

    def c = 1
    println c.getClass().getName()

    def b = 1.1
    println b.getClass().getName()

    def a = 1.1d
    println a.getClass().getName()

    ============================================================================
    Output


    groovy> class Name {
    groovy> String id = "Sargis"
    groovy> }
    groovy> def name = new Name()
    groovy> println name.id
    groovy> println name.getId()
    groovy> println name['id']
    groovy> def c = 1
    groovy> println c.getClass().getName()
    groovy> def b = 1.1
    groovy> println b.getClass().getName()
    groovy> def a = 1.1d
    groovy> println a.getClass().getName()

    seems everything is ok

  • Avoid list.each{}, prefer for (a in list)
