Here is the code:

foreach my $curr (@allwords) {

@allwords = keys %seen;
my question is: what will @allwords now contain, or how would the entries in the @allwords array be different after this manipulation?

business::onlinepayment::https
OnlinePayment::HTTPS(3pm) User Contributed Perl Documentation OnlinePayment::HTTPS(3pm)
NAME
Business::OnlinePayment::HTTPS - Base class for HTTPS payment APIs
SYNOPSIS
package Business::OnlinePayment::MyProcessor;
use base qw(Business::OnlinePayment::HTTPS);
sub submit {
my $self = shift;
#...
# pass a list (order is preserved, if your gateway needs that)
( $page, $response, %reply_headers )
= $self->https_get( field => 'value', ... );
# or a hashref
my %hash = ( field => 'value', ... );
( $page, $response_code, %reply_headers )
= $self->https_get( \%hash );
#...
}
DESCRIPTION
This is a base class for HTTPS based gateways, providing useful code for implementors of HTTPS payment APIs.
It depends on Net::HTTPS::Any, which in turn depends on Net::SSLeay _or_ ( Crypt::SSLeay and LWP::UserAgent ).
METHODS
https_get [ \%options ] HASHREF | FIELD => VALUE, ...
Accepts parameters as either a hashref or a list of fields and values. In the latter case, ordering is preserved (see Tie::IxHash to
do so when passing a hashref).
Returns a list consisting of the page content as a string, the HTTP response code and message (i.e. "200 OK" or "404 Not Found"), and a
list of key/value pairs representing the HTTP response headers.
The options hashref supports setting headers:
{
headers => { 'X-Header1' => 'value', ... },
}
https_post [ \%options ] SCALAR | HASHREF | FIELD => VALUE, ...
Accepts form fields and values as either a hashref or a list. In the latter case, ordering is preserved (see Tie::IxHash to do so when
passing a hashref).
Also accepts instead a simple scalar containing the raw content.
Returns a list consisting of the page content as a string, the HTTP response code and message (i.e. "200 OK" or "404 Not Found"), and a
list of key/value pairs representing the HTTP response headers.
The options hashref supports setting headers and Content-Type:
{
headers => { 'X-Header1' => 'value', ... },
Content-Type => 'text/namevalue',
}
