Putting arrays in quotes seems to be the same as joining them. That is, it adds spaces betweeen the elements.

Array interpolation uses $" as the separator, which defaults to a space, but can be changed to anything. Thus, "@array" is equivalent to join($", @array) (which I had in my earlier reply, but didn't really explain all the way).
