Perl 6.c!!

Thank you Perl 6 devs--what a great Christmas present! Now I'm looking forward to buying my first paper copy of a Perl 6.c book. Any rumours of who/what/when out there in Perl 6 land? Best, -Tom

Perl 6 Module and Program File Extension Conventions?

In Perl 5 it seems the prevailing convention (in my experience) is to use ".pl" for Perl programs and ".pm" as file suffixes for Perl modules. In Perl 6 I have seen in the various repos, blogs, and doc both ".pl", ".p6", and ".pl6" for programs and both ".pm" and ".pm6" for modules. Is there any

'!' versus 'not' in boolean expression

In creating some new Perl 6 programs I've run across several instances I'm confused about, to wit: Example 1 --- > my %h; say 'false' if !%h:exists; Unexpected named parameter 'exists' passed Example 2 --- > my %h; say 'false' if not %h:exists; false It looks like '!'

Is there another way to define a regex?

I'm trying to write all new Perl code in Perl 6. One thing I need is the equivalent of the Perl 5 qr// and, following Perl 6 docs, I've come to use something like this (I'm trying to ignore certain directories): # regex of dirs to ignore my regex dirs { \/home\/user\/\.cpan |

I would like to see such a list. It would help separate some of us bloviators, dreamers, and hand wavers from the others on the users list. -Tom

A practical benchmark shows speed challenges for Perl 6

I use Perl for heavy duty text processing. A question on Perl Monks about Perl 5's handling of a large input file got me wondering how the two Perls compare at the moment. I wrote a couple of simple programs, in both languages, to write and read a 10 Gb text file filled with identical
