While there is no doubt Closures are very powerful concept they are fairly complex to implement properly and efficiently.
However, one of the use cases, control block can be simulated using the for each loop without limiting functionality of the blocks involved.

When the loop break unexpectedly, there is no guarentee when, if ever, the iterator will be closed/finalised."

A solved problem, circa 1983. Implementing closures is of known complexity. In fact, Java already has an implementation in the compiler, otherwise how would anonymous classes access things from their enclosing scope?
