Consider this oft-repeated pattern:

 dim items() as string = Array(...)
 for each item as string in items()

Why is "as string" necessary in the "for" statement? I'd rather  
just say:

 dim items() as string = Array(...)
 for each item in items()
    ...
 next


How about

 dim items() as variant
 .... fill the array somehow ....

 for each item in items()
    ...
 next

What type should "item" be ?

It would be a variant, I think, as in old versions of VisualBasic.  
Currently, VisualBasic uses a For...Each construct similar to Rb's,  
requiring dimensioning of the control variable prior to or within the  
For...Each statement, and most collection types support For...Each 
(ie., arrays, collections, hashtables).

Best,
