Return from the Closure

the code:

class test {
    lt = ['a','b','c']
    find1(value){
        lt.each ({
            if (it == value){
                return "1:${it}"
            }
       })
       return '1:not found!'
    }
    
    find2(value){
        for (item in lt){
            if (item == value){
                 return "2:${item}"
            }
        }
        return '2:not found!'
    }

    static void main(argv){
        ins = new test()
        println ins.find1('a')
        println ins.find2('a')
    }
}

result:

1:not found!
2:a

I find when to be return from the Closure, it actually break the loop,
and can't return from the method. I think this not like usual habit,
please provide the opinion

thanks.
