Thinking about which database to use with Raku, I started following a question

From that page I learned that there are both "trusted" and

Just want to elaborate on the two different ways of combining statements
mentioned earlier.
1A. If you're using `-pe` command line flags, you use `s///` and combine
statements with `;` semicolon:

lilacs are blue

Hi Todd!
In the Raku REPL (MoarVM 2023.05):
[0] > my $x="abc2def"; say $x ~~ / ^ ** 7 $ /;
｢abc2def｣
alnum => ｢a｣
alnum => ｢b｣
alnum => ｢c｣
alnum => ｢2｣
alnum => ｢d｣
alnum => ｢e｣
Won't adding a `\n` newline to the `spurt()` call eventually cause problems?
What happens if you omit the `\n` below?
Best, Bill.

Hello,
While playing around in an attempt to define new operators, I stumbled upon
some curious results.
In the REPL, trying `say :_` returns a blank line.
In the REPL, trying `say :_:` returns `_ => True`.
What is the meaning of this?

Hi, I'm seeing an issue where I try to write parallel code between `slurp`

vertical whitespace (but not horizontal whitespace), the two methods will
be differentiated--since lines autochomps by default.

Hi Marc (and Bruce)!
I'm adapting a "word frequency" answer posted by Sean McAfee on this list.
The key seems to be adding the `:exhaustive` adverb to the `match` call.
AFAIK comb will not accept this adverb, so `match will have to do for now:
Sample Input (including quotes): “A horse, a horse,
It seems to work okay if I change `num` to `Num`:
class A {
has Num $!a is required is built;
};
dd A.new(a => 0e0);

Hi Marc,
My understanding is that ranges are pretty cheap to construct, and in any
case, the range @x[0..*-1] is just the index of all elements in @x. The
.grep() approach may be most useful if you have a function (e.g. %, %%, and
.is-prime shown below):

Possibly relevant StackOverflow question:
"Why does constraining a Perl 6 named parameter to a definite value make it
a required value?"

Hi,
I'm trying to put an answer together for SO, and I keep running into the
same difficulty. Given a CSV file, how can one produce an XML file with
latitude and longitude values properly quoted? Every time I get proper
quoting, "lat" and "lon" are scrambled (i.e. sometimes "lat" first,

Hi Aureliano!
Backing up a bit (and since you're favoring an array data structure), we
had a discussion on StackOverflow regarding implementing R's concept of
"named vectors" in Raku. See:
"Is there a convenient way to replicate R's concept of 'named vectors' in
Raku, possibly using Mixins?"
Hi, I've recently updated my Rakudo installation, and I wanted to test
multi-line input in the REPL. By mistake I entered a backslash at the REPL

Hi Bruce,
This is what I see with Rakudo 2020.10 (all code below performs
delightfully as expected):

Hi Andy,
A quick test with my (older) Raku install and I was able to get one of the
examples (Daniel's) below to work. However I had to use "Int" instead of
"int":

Joseph (and Ralph): thanks for starting off this conversation!
Fernando and Vadim: amazed at your code!

I tried this--from your original file, not your most recent attempt--and
couldn't get it to work. If you look below, "mothera" never gets excluded,
except the last test (Exclude4), which is the control case (single regex,
no any junction):
my @exclude1 = ( rx/<|w>mothera$/, rx/<|w>camel$/ );

I started trying to explore enums on my own and quickly realized that
method calls on enums are different from simple key/value pairs. For enums,

If I imagine that ":eager" is an adverb modifying take(), it fails:

Hi Yary,
I ran your Raku code in a script (on MacOS) and in the REPL (MacOS with
Linenoise). All results below with Rakudo_2020.10:

my $word = /(\w+)/;
my $AwithB = /$word' with '$word/;
$_= 'Interpolating regexes with arbitrary captures is fun!';
say "Nested rx";

Dear Brad,
1. The list you posted is fantastic ("If the first character inside is
anything other than an alpha it doesn't capture"). It should be added to
the Raku Docs ASAP.
2. There are some shortcuts that don't seem to follow a set pattern. For
example a named capture can be accessed using $

The simplest solution seems to be reviving the historical

I think the priority should be keeping the community together and
gradually migrating to a more appropriately-named list, possibly
running dual lists for a while make sure we don't lose anyone in the
