I don't think that is a good idea.
Since Iterator::Diamond is intended to behave like <>, it must operate
on global @ARGV, $ARGV and ARGVOUT. When you can say:
$input = Iterator::Files->new(@filelist);
you can also say:
$input1 = Iterator::Files->new(@file1list);
$input2 = Iterator::Files->new(@file2list);
and things would terribly screw up.
Besides, it is very easy and straightforward to write:
{ local (@ARGV) = @filelist;
$input = Iterator::Files->new;
while ( <$input> ) { ... }
}
Alternatively, I could limit the use of @ARGV, $ARGV and ARGVOUT to
the case where no explicit file list is used.

Thanks.
