Why I’m Learning Perl 6

I hate perl6. I hate it because I tried to get involved in the project early on, and it led me down the Haskell rathole. I don't know what Haskell looks like today, but a decade or more ago it was the hardest language to pick up that I had ever experienced. It was as if I had a solid background in latin languages and I was trying to pick up Chinese based on a handful of tutorials written by a tourist on the back of a…

The Haskell introductory landscape has definitely changed. Learn You A Haskell for great good ( http://learnyouahaskell.com ) is an excellent introductory book to read to get started with Haskell. A drier but more in-depth read is http://book.realworldhaskell.org/ Also, when you hit monads again, the best advice I can give you to understanding them (99% of Haskell guides out there seem to be about monads) is to take…

Perl6 is no longer implemented in Haskell on the backend. I think the old parrot VM was, but MoarVM is in C. On the bright side, a lot of cool FP concepts made it into P6 as a result of the original Haskell backend, so useful cross polination happened. Even better, you can do FP stuff in a much easier to understand way and you can also mix in OO when needed or relevant.

I think the old parrot VM was Parrot was implemented in C, and to my recollection implemented various iterations of bytecode syntaxes, notably PBC (parrot byte code). Rakudo Perl 6 developers took the route of developing Perl 6 through an intermediary language NQP, which is a language aimed at making it easy to implement interpreted languages. Rakudo (the im…

Perl6 is indeed a very nice language that I've been watching for a few years. As soon as the performance beats Python and the stability is solid I'll probably switch over from Python...there's just a lot there.

I have seen examples where the naive Perl 6 implementation is faster than the equivalent C code. (The one I'm thinking of is probably owing to Spesh and the JIT, but I forget what it was about) Here's an example where a naive Perl 6 version is going to beat the pants off of the naive version in another language: Find the sum of all integers from 10 to 1000000 inclusive. In Perl 6: say [+] 10 .. 1000000 the [+] is a l…

Why are the awk guys to blame for Perl syntax?

> Concurrency is hard and if you want M:N thread multiplexing (i.e. WEB SCALE CODE, where application threads aren’t pinned to pthreads) your options today are precisely Erlang, Go, .NET, and Perl 6. Putting aside the "web scale" jokes ( http://www.mongodb-is-web-scale.com/ ), this statement is still absurd. Every major language, or at least the ones that matter for backend development, has support for thread multipl…
