I think the current flattening aspect is awkward in a couple ways:

Hi all,
Thanks Bill for posting your results from my samples. Seems like we both
get lots of warnings/errors from our REPL's, me even with 2021.02.01. I

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:
#Script:
my $word = /(\w+)/;
my $AwithB = /$word' with '$word/;
$_= 'Interpolating regexes with arbitrary captures is fun!';
say "Nested rx";
dd m/$AwithB.*'is '$wo

Fyi, here's how Larry Wall expressed it 15-18 years ago:

A Raku equivalent:
my $word = '(\w+)';
my $Awi
My current expectations are a little different than any others previously
expressed and I don't know how to get the result. I am no longer
considering named captures from Regex's interpolated inside and am now looking at directly interpolating them.
Perl example:

I can confirm your new test code also works fine in both program

Not the list, right? Just the rule. (There are dozens of kinds of
assertions. No one
is going to remember the list.) If you wer
And when I cut/paste from the doc, the number example works too,
in both script and repl.

Er, by wfm I mean it matches ｢Is｣ as the code suggests.

The "Interpolation" section of the raku docs use strings as the elements of
building up a larger regex from smaller pieces, but the example that looks
fruitful isn't working in my raku. This is taken from

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 $ i
And once again, thanks much for the explication of all this...
But even after thinking it over, the current state-of-affairs on
this really doesn't strike me as being okay.
As I'm sure everyone here knows, over in perl-land the main trick
you have for creating regexes from components is lexical
in
It makes <…> more consistent precisely because <$pattern> doesn't capture.
If the first character inside is anything other than an alpha it doesn't
capture.
Which is a very simple description of when it captures.
doesn't capture because of the ｢?｣
doesn't capture because of the ｢!｣
Thanks much for your answer on this. I think this is the sort of
trick I was looking for:

That's good enough, I guess, though you
If you interpolate a regex, it is a sub regex.
If you have something like a sigil, then the match data structure gets
thrown away.
You can put it back in as a named

｢9 million｣
pattern => ｢9 million｣
0 => ｢9｣
1 => ｢million｣
Or as a numbered:
