| * Bug illustrating the nested closures variable scope visibility issue. |
| * l.each is ClosureInClosureBug$1 and it.each is ClosureInClosureBug$2 |
| * The variable text is not visible from ClosureInClosureBug$2. |
| * Indeed, a closure can only see the variable defined outside this closure (one level up) |
| * but cannot see what's in the second level. |
| * |
| * In order to make the test work, do not forget to uncomment the line "println(text)" |
