Shame it's slower than existing work. We know pretty well how to optimise dynamic languages these days.
They still have no idea how a fast dynamic language should be designed. To their advantage python does neither. Ruby does know, but doesn't get along with to well. Only PHP got their act together with 7.0.
I'd be interested to see what features there are that make the system slower in general, even when they aren't being used. I did a lot of work in my PhD on making odd features not affect the performance of Ruby code when they aren't being used.
Do you know what they are?
Do note that you will have to look closely and follow references to make sure you have a full picture of understanding, since at first glance many of them seem simple, but turn out to offer considerable depth.
Really, there hasn't been a terrible amount of new features in Perl 5 - and certainly not a new model for OO. Moose is great! And the constant release of CPAN modules is also wonderful, but the core of Perl 5 is full of dragons, which makes backporting features from Perl 6 hard to do in core - and perhaps a good argument can be made against doing that. Example: Moose is a very successful project, but thee given/when statement in the core of Perl was a failure.
CPAN is the language, perl is just the VM.
* multiple dispatch * the meta-object protocol
And the thing is, these features are being used all the time, because the core language is built out of them. If you want to see how a language which is not built on these things runs (on the same vm implementation, I might add), I suggest you try nqp :-).
I've come up with rather 'creative' workarounds[1] until a more proper solution arrives...
