I understand what you're saying Abigail, and it makes absolute sense that if all you want is an array interpolated into a string with single spaces between elements, you'll use "@array". But he was trying to sort, and wanted the results to be output with single-spaces between each element. Fine, but he was going about it by inventing syntaxes that simply didn't do what he wanted. For one, putting "@array" in quotes as an argument to sort.

And though interpolation has its place, you probably wouldn't recommend this (except for maybe in an obfu:

print "@{[sort @array]}";

Or maybe you would. There is always more than one way to do it. Though this method probably creates two copies of @array; one being an anonyomous array, and the second being the interpolated string.

Anyway, thanks for pointing out the overstatement of my post. You are (as is often the case) correct.
