Hi Radhakrishnan,
I think the question you are asking directly relates to your
experience as a programmer. If you have a lot of experience and a
"systems programming toolkit" under your belt (classic bash shell
scripting, sed, awk, and perl_5 ), what does Raku/Perl6 add? The short
answer is:
True, and I am well and truly baffled by my example where the 1st bad line
incorrectly is labelled good, the 2nd bad line is correctly labelled bad,
and the 3rd good like is correctly labelled good.

Oh, but if you go literally with the code I posted, *both* the first
and second lines have incorrect descriptions, and only the third line
("corn dogs") matches.

Getting correct behavior is an improvement over my try like so, which
gets the same warning but fails all the lines:

There is potentially a place for Raku in education, as a language that
can evolve from simple expressions in the REPL to one-liners, basic
scripts and through to complete CS courses with the various
programming paradigms (procedural, O-O, functional) and into language
design with grammars.
The
By the way, I've been finding code assertions are a fun way of
spying on what's going on with your regexps:
$_ = "Alpha beta gamma";
my @matches = m:g/(a) /;
# 5
# 10
# 13
# 16
I should have read the output!
This one gives the right answers but with lots of warnings

Well, with the first one it rejects all of my lines, and with the
second one it passes all of them.
Just to be be clear, my idea is the second line is wrong, and it
should flag that one as a problem

Try matching against / (^P\d+) \s+ %products{$0} /
This one also works, in a roundabout way

In part because of the recent discussion here, I decided to
play around with using Raku code embedded in a regexp.
I came up with a contrived example where I was going to
examine a product listing in a text block to see if the product
descriptions matched the product codes. The valid associations

Perhaps I read an interesting point mentioned by Richard:

I would be considered a non-developer and more of a system admin/architect.

Hi,
If you allow me to jump in.
I have used scores of programming languages. For me, raku (as it is now
called) is the language to go to if I need a serious textual analysis of
any kind.
The design aspect of the language that I rely on heavily is the Grammar
class, which so fundamentally
