What if I have a data structure that is logically iterable yet not a Collection nor an array? How would I use for in say, a Vector or Matrix class of my own design? What if I wanted that for loop to iterate over the elements of a Matrix in some nonstandard denumerable manner?
It would seem more logical to me for Java to simply apply allow blocks as used in Smalltalk.
