# Code where sub is defined:

use Exporter();
my @ISA = qw/Exporter/;
my @EXPORT = qw/&getData/;

sub getData
  {
    # do stuff
    # return a hash
  }


# Package declarations - none, that I'm aware of.  Never
# had this problem before, using &Reader::getData and the 
# like.

# Failing call:

use Book::Reader;
my $hashref = &Book::Reader::getData;
