The SF Perl Raku Study Group, 04/10 at 1pm Pacific Time
Note: Here in the US, we are about to "spring ahead" one mooorre time, and the 1pm I'm referring to is an hour earlier than many of you expect. "It's becoming increasingly unusual to read a report of a new technology or scientific discovery that doesn't breathlessly use the phrase 'it seems like science fiction'. The news cycle is currently dominated by hype about artificial intelligence (a gross mis-characterisation of machine learning algorithms and large language models). A couple of years ago it was breathless hype about cryptocurrency and blockchain technologies-- which turned out to be a financial services bubble ...

And now 4:
$ raku -e '.say for .sort: {m/ \d+ /.Int}'
bk1
bk2
bk10
bk34
or, same logic, but spelled differently:
$ raku -e '.say for .sort: +*.match: / \d+ /'
bk1
bk2
bk10
bk34

Re: pint: Elizabeth, sort list???
hello,

ok … so I'm lost but I'm not even curious to understand why (because of
my lack of interest for the ==> operator :))

Re: pint: Elizabeth, sort list???
Hi Marc,
This works:
==> sort({ | map { +$_ // $_ }, .split: /\d+/, :v }) ==>
say()
As the documentation says here https://docs.raku.org/routine/%3D%3D%26gt%3B
The precedence is very loose so you will need to use parentheses to assign
the result

hello,

I tried
< afoo12 afoo2 >
==> {.sort: { | map { +$_ // $_ }, .split: /\d+/, :v }}
==> {map }
and the error message is really interesting
Only routine calls or variables that can '.append' may
appear on either side of feed operators.
on the other hand: I really don't understand why ==> even exists
as method call syntax works well.
< afoo12 afoo2 >
.sort( { | map { +$_ // $_ }, .split: /\d+/, :v } )
.map()
what I would love instead is something closer than the haskell's $
operator with a very low priority so it could be possible to be
parenthesis free.
as example. I would like
1..10 ==> map * * 2 ==> say
to be a joyful version of
(1..10).map(* * 2).say
