...And Now for Something Completely Similar, by
TheDamian.
So let’s calmly back away from all those snarling differences, and turn our attention instead to the many aspects of Perl 6 that are staying the same (or, at least, reassuringly very similar).
To do that, we’re going to make some of the Perl 6 design team “eat their own dog-food”. That is, we’ll take a few real-world Perl 5 programs that Nathan Torkington, Hugo van der Sanden, Dan Sugalski, Simon Cozens, and I use every day, port them to Perl 6, and see how much they actually change.
Damian showed
us entar and
untar as examples of how he customizes his enviroment. Very cool.
