A program with arrays that are tied in one place and not in another has bigger
problems than this anyway. But I don't see a problem with using $" with tied
arrays, unless the tied class happens to overload stringification.
print join(',', @array), "\n";
is a lot noisier and IMO clumsier than
{
local $" = ',';
print "@array\n";
}
and after all, even if you don't know what $" does it's very simple to look it
up and also easy to remember.
