Comments on: Day 19: Whatever http://perl6advent.wordpress.com/2009/12/19/day-19-whatever/ Something cool about Perl 6 every day Sun, 03 Feb 2013 05:15:50 +0000 hourly 1 http://wordpress.com/ By: Moritz http://perl6advent.wordpress.com/2009/12/19/day-19-whatever/#comment-212 Wed, 23 Dec 2009 17:46:21 +0000 http://perl6advent.wordpress.com/?p=158#comment-212 It seems there is a bug in Rakudo that prevents * ~ "a" from working – I’m sorry, I should have checked that before writing my post.

my @x=1,2,3,4,5;
say @x.map: *+2; # outputs: 34567

But not this?:
my @x=;
say @x.map: * ~ “a”;
# outputs: No applicable candidates found to dispatch to for ‘map’ in Main (file , line )

(Actually there’s a slight difference, a pointy block will return a Block object, and *-5 a WhateverCode, but both should work for array indexing)

say @array[-> $x { $x-5 }];
too?
Or even
my $make-index = -> $x { $x-5 };
say @array[$make-index];
?
