This is a quick & dirty implementation of a LWP::Simple clone for Rakudo Perl 6.
Since Perl 6 is a bit new, this LWP::Simple does both get and post requests.
LWP::Simple depends on the modules MIME::Base64 and URI, which you can find at http://modules.perl6.org/
As of 2011-04-22, runs with all recent rakudo builds. It correctly follows redirects, but no infinite redirects detection yet.
