Okay!

BTW, does Gambas use exclamation points (!) for anything?

In Ruby, some methods are named with an exclamation point to indicate 
that they modify some data.

Applied to Gambas, it would work like this:

   newArray = myArray.Reverse ' return a reversed array
   myArray.Reverse!           ' reverse this array!

   newArray = myArray.Sort ' returns a sorted array
   myArray.Sort!           ' sort this array!

   newString = myString.Reverse ' returns a reversed string
   myString.Reverse!            ' reverse this string!

I know this isn't BASIC as we know it, but it's an interesting idea 
nonetheless.
