in thread array sorting

Don't rely on that sort of thing (string interpolation, etc).
Huh? Why is that? Does string interpolation only work half the time?

I prefer "@array" over join " ", @array any day, and twice on Mondays. It's less messy: 

    print "The first results are [@first]; the second are [@second]\n"
+;

vs. 
    print "The first results are [", join (" ", @first),
          "; the second are [", join (" ", @second), "]\n";

And pity you if you forget to leave off a set of parens.

    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.
