Subject: | please don't use indirect object syntax |
The documentation uses indirect object syntax which is considered bad
practice since some years already.
See 'Indirect Object Syntax' in
http://perldoc.perl.org/perlobj.html#Invoking-Class-Methods and
http://www.network-theory.co.uk/docs/perlref/perlobj_Indirect_Object_Syntax.html
for an explanation.
