moritz_ good localtime() ;)
masak moritz_: good localtime() 08:59
though ours is roughly the same, I'd guess
moritz_ masak: I think we are in the same time zone (GMT+1)
+ 1h DST or something
masak let's see
it's not daylight savings...
yep, same time zone
moritz_ 11AM right now
masak correct
masak is doing haskell today 09:00
moritz_ masak: so I can wish you a good moritz.localtime() ;)
masak moritz_: likewise :)

Aankhen`` Beware the Jabberwocky. 09:01
masak :)
I'm currently operating along the principle: 09:02
"If you have to specify base case and recursion case, then you probably missed a useful function in Prelude"
it's working exceedingly well
moritz_ the question is: does it improve readability? 09:04
masak moritz_: in a way, no 09:05
because it depends more heavily on Prelude
actually, it depends
I had a function that searched through a list, and I replaced it with `lookup`
great improvement, even in readability

masak mind you, perl 6 contains many cool things
but regexes are so very powerful in p6 09:17
moritz_ they are indeed ;)
but sometimes I wonder if all that power is really needed except when writing "real" parsers
anyway, shower & 09:18
masak moritz_: seems to me that many programming problems converge towards being "real" parsers anyway
so, might as well have the tools for it
take something as common as reading a HTML file 09:21
wham, recursive regexes needed

I figure I'm reinventing every wheel possible anyway, I might as well do this one too.

Aankhen`` It's a learning experience.

Aankhen``: looking
Aankhen`` At present the AST indicates prefix:<|>… is that the correct way to do it? 19:23
I'm a little confused with regards to captures and splicing arguments, as you may have noticed. :-) 19:24

Thanks for the example, though; I'd been scratching my head over how to use &map. 19:28
