I am using a module having documentation saying document() is a

$o->document;
Can you reference a method in this way? (I takes no args). I always
thought
$o->document() and $o->document meant different things, function
verses attribute.

To call subroutines:
NAME(LIST); # & is optional with parentheses.
NAME LIST; # Parentheses optional if predeclared/imported.
&NAME(LIST); # Circumvent prototypes.
&NAME; # Makes current @_ visible to called subroutine.
