Description
"Originally designed as an exercise in addition for students, the Fibonacci Sequence has some really interesting mathematical properties. While completely ignoring its unexpected niftiness (and explicit formula), this miraculous sequence is still used as busy work for poor creatures."

What can I do with Perl 6 today?
What can YOU do with Perl 6 Now, Today, This minute?
Introduction
- Add tasks, exercises, and projects that can be done today with perl 6.
- Include brief explanations:
- How to run?
- What is required?
- Cite benchmarks (e.g. vs Perl 5, Python, Ruby, etc.), if possible.
- Each item should link to a page that gives a summary of its status (possible, buggy, depends on X) and includes or links to examples, benchmarks, articles, code, etc.
- Some places to check for potential content ideas:
Run Some Code
- Get and make Rakudo:
- Get and Make parrot
- svn co https://svn.perl.org/parrot/trunk parrot
- perl ./Configure.pl
- make
- use parrot languages/perl6/perl6.pbc some_code.p6
- Try make perl6 and then you can use ./perl6 some_code.p6
- Download some perl6 examples (from the github perl6-examples repo)
- git clone git://github.com/eric256/perl6-examples.git
- Download more perl6 examples (from the pugs repo)
- svn co http://svn.pugscode.org/pugs/examples/

Description
Invented by the French mathematician Édouard Lucas in 1883, this is a mathematical game/puzzle about moving a set of disks between a set of pegs, limited by the following rules :
- Only one disk may be moved at a time.
- Each move consists of taking the upper disk from one of the pegs and sliding it onto another peg, on top of the other disks that may already be present on that peg.
- No disk may be placed on top of a smaller disk.

- Parrot SVN Revision 24478 3 January 2008 : works as is
- Pugs SVN revision 18224 : works as is
Benchmarks
1000 iterations with 6 disks - skip output ( or comment on output to file, etc : http://sial.org/pbot/29516 thanks to Stephen Weeks / Tene on #perl6 )
