IIya - I ran into a regarding lambda scoping in a DSL I'm working on, similar to the issue you were discussing the other day.  In my use case, unintuitive things happen when the `this` from an outer scope is implicitly used in an inner-scope. I'm making a framework for defining nested validators for objects, but its basically written very similarly to the HTML Builder example. 

```
outer() {
    doOuterThing() // fine, implicitly the same as the following two statements
    this.doOuterThing() //fine
   this@outer.doOuterThing() // fine

   inner() {
       doInnerThing() //fine, implicitly is this@inner.doInnerThing()
       doOuterThing() // bad, because it is implicitly this@outer.doOuterThing().  Causes weird stuff to happen
  }
}
```
