[Gambas-user] variable declaration everywhere ???

Well, lets just get out of the box here (or outside the nine dots, if 
you get my idea)

(BTW, I just picked this as a rational point in the thread.)

The only cogent argument that has been presented by the entire brains 
trust here is that it would be handy, really handy, to be able to 
"declare indexers for an array loop on the fly".

So, here's a couple of (possibly stupid) ideas.

1) For Each <array>
      do something
    Next
   ' No indexer, no garbage, the implied indexer would only have scope 
inside the loop.

2) Less personally favored but possibly useful:
   For idx as Integer = -Infinity To Infinity ' or some other bounds 
that are meaningful.
     <array>[idx] 'do something
   Next
   ' idx survives, but only until it is next proposed as an indexer

I mean, just because "some other language" proffers the opportunity to 
create gibberish code, it doesn't mean that Gambas has to.  In fact, 
further, why not create something new and useful?

Anyway, just my thoughts. (Thanks Rolf! You crystalised what I was 
trying to think about.)
