This doesn't actually work, for obscure reasons having to do with parsing
and such. It's documented thusly in perldoc -f print:
Note that if you're storing FILEHANDLES in an array or other
expression, you will have to use a block returning its value
instead:
print { $files[$i] } "stuff\n";
print { $OK ? STDOUT : STDERR } "stuff\n";
In other words, print can't handle anything other than a simple scalar value
as its filehandle argument, unless you use the above block form.
