The output of "perldoc -f print" contains the following phrase:
If you're storing handles in an array or hash, or in general
whenever you're using any expression more complex than a bareword
handle or a plain, unsubscripted scalar variable to retrieve it,
you will have to use a block returning the filehandle value
instead, in which case the LIST may not be omitted:
If "STDERR" isn't a bareword, then which bareword is this phrase
referring to?
