tadzik next to 'sub RESET is export { "\e" }' and friends in Term::ANSIColor 10:38
masak looks 10:39
sure, you could make those macros. but honestly, they look like highly inline-able functions to me, and so it shouldn't really matter. 10:40
by the principle of least power, you should probably keep them as subs and lobby for excellent inlining. 10:41
tadzik hm 10:44
indeed, being inlinable subs they'll probably end up being the same thing in the generated code
masak right. 10:45
so... Better Written As Sub. :)

15:26 Mescale left
TimToady this often means the function should be using gather/take rather than pushing to an array :) 15:26
grondilu indeed it should return a list in my example, not an array.
my bad 15:27
TimToady though 'return @array' should be returning it as a list
no problem; we're all still trying to figure this out on one level or another... :) 15:28
grondilu the thing is my function as returning a list of arrays, and at some point this confused me into thinking I should dereference the output.
which was wrong.

Tennessee is pretty straight though...
azawawi jnthn: Is Perl6::Compiler accessible from within a Perl 6 script?
jnthn azawawi: No
Well, OK, not by that name. :) 15:37
That'd be a confusion of compiler vs compilee scope :)

Friendofafriend so... whens perl 6 coming out? 20:01
ALSO where are some good tutorials for learning perl 5
?
TimToady coming out of what?
Friendofafriend Larry Wall's brain
flussence by "release", do you mean 10 years ago, or 4 years ago? 20:02
TimToady Larry Wall's brain doesn't even know when Perl 6 will quit flowing outward...
the flow seems to have slowed considerbly over the last couple years, and the implementations are starting to catch up 20:03
Friendofafriend gotcha
TimToady bbq & 20:04
Friendofafriend well in that case.. do you know of any good perl 5 tutorials / books ?
im trying to learn perl
rking Friendofafriend: I still advocate the Camel book.
Friendofafriend which one? 20:05
masak the latest one :) 20:06
rking Friendofafriend: www.amazon.com/Programming-Perl-Unm...camel+perl
Friendofafriend haha thanks for the link
yeah Larry Wall just talked at my school, so im kinda motivated
rking Friendofafriend: What did he talk about?
Friendofafriend just how perl came to be. 20:07
and why it is the way it is
it was a great talk
he explained the linguistic origins of perl
it was very cool 20:08
masak oh, Westmont college?
Friendofafriend indeed
masak we think Perl is cool, too. 20:09
Friendofafriend haha
how did you know about westmont?
masak Larry Wall is a friend of a friend... :P
I agree that the Camel book is hard to beat in terms of learning material.
it's sitting here on my shelf within arm's length. 20:10
Friendofafriend haha yeah, Im pretty good friends with his son, lewis
masak I know him as quietfanatic, but yes, I talk to him sometimes, too.
rking Friendofafriend: The `perldoc` information is actually excellent.
masak `perldoc` is excellent, but kinda difficult to bootstrap up from 0 with.
IIRC `perldoc` is actually based on the Camel book somehow? 20:11
Friendofafriend yeah hes a great guy, I pair program with him quite a bit, and have learned so much
rking Friendofafriend: What kind of programming is he into?
masak Friendofafriend: this is kind of the "future department" of Perl, in case you're wondering. we've been inventing the future of Perl for the past 12 or so years. 20:12
Friendofafriend just mostly school projects
ie weather servers written in raw c
blah
masak Friendofafriend: I've taken to discussing language design with him, which is also very interesting.
Friendofafriend yeah, hes started writing his own language

raiph "Metacircularity is not about self-interpretation at all. Rather, it's an engineering approach to re-using as much code as possible between different parts of a toolchain (including compiler, runtime and debugger)." (from www.inf.usi.ch/postdoc/kells/blog/2012/06/01/) Anyone care to agree/disagree/comment on this perspective and/or its applicability to Perl 6? 20:14
masak raiph: we've definitely been seeing that aspect of metacircularity now and then, both in Niecza and Rakudo, I think. 20:15
though whether to elevate it to what metacircularity "is about", I don't know.
jnthn raiph: Well, in my meta-programming in Perl 6 talk, I define meta-circularity as extending the langauge using the language itself. 20:16
raiph: Which seems compatible with that point of view.
