vit has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,
After starting using Parallel::ForkManager I am getting
Anonymous function called in forbidden scalar context; faulting at c:/ +ActivePerl/site/lib/Lingua/EN/ line 199
in Lingua::EN::Tagger in the following place:
sub add_tags { my ( $self, $text ) = @_; return unless $self->_valid_text( $text ); my @text = $self->_clean_text( $text ); my $t = $self->{'current_tag'}; # shortcut ### I am getting this in this line: ####### my ( @tags ) = map { $t = $self->_assign_tag( $t, $self->_clean_wor +d( $_ )) || $self->{'unknown_word_tag'} || 'nn' +; "<$t>$_</$t>" } @text; $self->{'current_tag'} = $t; $self->_reset; return join ' ', @tags; }
I printed out @text and it is fine. It may not be directly related to using Parallel::ForkManager. Data is correctly passed to tagger.
So what can cause this error? Any thoughts?

    Are you (or your modules) using Memoize? Google returns many hits with this module.
        Are you sure? From the source:

        package Lingua::EN::Tagger; our $VERSION = '0.16'; use warnings; use strict; use Carp; use File::Spec; use FileHandle; use HTML::TokeParser; use Lingua::Stem::En; use Memoize; use Storable;
