It's not a serious warning -- the program is doing what you coded it
to do, and you can supress it by explicitly mentioning the filehandle in the
print
print STDOUT (('January' ..... );
To understand why, perldoc -f print
Here is an example of what that warning is trying to warn you about:
......................... BEGIN PERL PROGRAM ............................
#!/usr/bin/perl
use strict;
use warnings;
my @list1 = qw / Red Green Yellow Blue / ;
my @list2 = qw / Rojo Verde Amarillo Azul / ;
{ local($, = ' ');
local($\ = "\n");
print @list1, @list2; # works
print (@list1, @list2); # works
print (@list1), (@list2); # gives warning and fails
print STDOUT (@list1), (@list2); # works again
}
.......................... END PERL PROGRAM .............................
And upon running, we get:
lawrence /tmp > perl test.pl
print (...) interpreted as function at test.pl line 15.
Useless use of private array in void context at test.pl line 15.
