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.
