Re: Looking for help updating Perl 6 and Parrot part of Perl Myths talk

[Tim Bunce]

I gave the talk at OSSBarcamp in Dublin last weekend and it went well.
My sincere thanks to everyone who contributed.

The slides are available at:

http://www.slideshare.net/Tim.Bunce/perl-myths-200909

The graphs and stats charting the continuing growth of perl and the perl
community were surprising (and delighting) even to me.  

The presentation was even featured on the slideshare.net home page for a
while. Yeah!

I'll be giving the talk again at HighLoad++ in Moscow in a couple of
weeks time, and possibly again at IPW09 in Pisa later in October (though
it's not been scheduled yet). So I'd be grateful for any feedback on
the talk. Corrections, improvements, extra data etc.

Thanks again!

Tim.

p.s. I've already fixed the suprious reference to CPANTS.

Thanks to masak's contribution we now have a plot containing also the
earlier history of proto, and is daily updated on http://rakudo.de/

It is not completely accurate, but it's a enough for a broad trend line.

I know the talk is over now, but maybe somebody wants to hold such a
talk in the future, too.

Should .^methods be curried with the invocant?

[Moritz Lenz]

Consider this case:

class A { method m { say 'OH HAI' } };
my $m = A.new.^methods(:local).[0];

How should I invoke $m?
In current Rakudo this works:
$m(A.new);  # supply the invocant as first argument

But shouldn't be just $m() (invocant magically curried) or may
$m(A.new:) (invocant not curried, but marked with a colon)?

Moritz

Methods are only methods when they are dispatched as methods, otherwise
they are regular subs. The invocant in the capture is just the first
positional argument, so $m(A.new) is what you want, although $m(A.new: )
should have the same effect.

Lenses?

[Timothy S. Nelson]

	I've been wondering about lenses recently.  The page at 
http://www.seas.upenn.edu/~harmony/ seems to give an overview, and I know that 
augeas also uses lenses.


	It seems to me that a grammar can be thought of as a one-way lens.  I 
was wondering whether the bi-directional idea might be interesting in this 
context.  It seems to me that, at the moment, when we want to do a format 
conversion, we:

-   Read the data in with a grammar
-   Output the data with something like Form.pm

	I'm wondering if there isn't some way that the whole thing can be 
turned into lenses.


	Anyway, I'm sort of half thinking out loud, and wondered if anyone had 
any relevant thoughts.
