is a lot noisier and IMO clumsier than

I disagree. Remembering what all these cussing variables do is not
easy. Just because you know what they are, doesn't imply that anyone
who has to maintain your code will know. Use English or use join.
use English;
{
local $LIST_SEPARATOR = ',';
print "@array\n";
}
Please don't recommend that beginner programmers use English without
supplying the caveat that it may break/slow down working code.
