Create a helper function Enumerations.asIterable()

[GoogleCodeExporter]

Please create a helper function to turn an java.util.Enumeration into a 
java.util.Iterable so I can write:

    Enumeration<Type> foo = ...
    for( Type e : Enumerations.asIterable(foo) ) { ... }

What about:
for (TimeUnit unit : EnumSet.allOf(TimeUnit.class)) { ... }

Or even:
for (TimeUnit unit : TimeUnit.values()) { ... }

Enumeration<Type> foo = ...
Iterators.forEnumeration(foo)

and then use Iterables or FluentIterable to do your stuff.

to comment #1 and #2:

java.util.Enumeration != java.lang.Enum

The issue with this is that Enumeration is single-use, like Iterator. So while 
you can create an Iterator from an Enumeration, you can't create a proper 
Iterable from one any more than you can from an Iterator.

Indeed, the Iterator as Iterable view is listed in the idea graveyard, and this 
would seem to fall into the same category.
