Smalltalk, Io and (possibly) Perl6 & Rebol are good examples of non-Lisp homoiconic languages which have full & robust metaprogramming.

Yep. And in Perl6 these were changed to: __LINE__ $?LINE __FILE__ $?FILE __PACKAGE__ $?PACKAGE __END__ =begin END __DATA__ =begin DATA ref: http://feather.perl6

And in Perl there are also: __FILE__ , __LINE__ , __PACKAGE__ , __SUB__ & __END__ These are called Special Literals - http://perldoc.perl.org/perldata.html#Special-Literals

... and called them .par or something? .par is already taken. See PAR, the Perl Archiving Toolkit, which attempts to replicate jar for Perl. - http://par.perl.org/ - https://metacpan.org/module/PAR

I think both camps will feel much happier when something like refinements are added to Ruby. In Perl I can safely localise all my monkey-patching by using dynamic scoping: sub today { DateTime->now } { no warnings 'redefi

Very nice indeed. NB. Correction to my earlier comment elsewhere here about List::Gen & multiple lists because it does provide cross combinators and also gather/take which is a perl6 way of doing complicated (multi) list comprehension

That's exactly how perl5 objects work: package Foo { sub new { my ($class, $bar) = @_; bless {bar => $bar}, $class } sub bar { my ($self, $x) = @_; say $self->{bar} . $x } } my $

Ditto for Perl with modules like List::Maker and List::Gen. However like the Ruby example this only works on a single list. Which reminds me that I keep meaning to write a port of CL loop in Perl using Devel::Declare. ref: https://metac

IMDb do have an API, for eg. app.imdb.com, however this is meant for mobile applications and it can only be used if authorized in writing(!) by IMDb. On CPAN there is WebService::IMDB module which uses this mobile API. Also there is IMBDB:

Moose ( http://moose.perl.org ) also provides the same mechanism via augment/inner . Here is one of the examples in Perl/Moose: package GameObject { use Moose; has ['x', 'y'] => (is => 'rw', isa => 'Num');

Considering perl5 is only 18 years old then somethings gone very awry there :) Perl6 is looking quite fresh considering how old you think it is. I just submitted an article I'd seen to HN which shows how a formula like... 4.7kΩ ± 5%
