Yeah, I was disappointed that that didn't work, and that what
did was relatively ugly, which is why I didn't bother to share it.

Hi Marc, There's also this conversation from March 2021 on the mailing list:
https://www.nntp.perl.org/group/perl.perl6.users/2021/03/msg9857.html
[Matthew's answer looks very interesting].
Anyway, HTH. --Bill.

I got that one and tried to generalize it with something more generic
(using * to get the number of elements).
thanks for helping

Hi Bruce and William,
Ineed: I was looking for [\,] but your code removes the anoying empty
string because of the leading / (which is awesome) so I mixed from both
answers (<-[/]> is more robust than .alpha ) and added .Str to .say.
finally I got:
<<. raku -ne '.Str.say for m:ex /^ ["/"

That won't match just a slash (`/`). Maybe:
.put for [\~] '/A/B/C' ~~ m:g { ('/'? <-[/]>*) }
And it'll treat `/a/b` and `/a/b/` as distinct if the input string is `/a/b/`.

[^1,^2,^3]
I could share a generalization but it's pretty ugly and I also think
it makes more sense to do something like Bruce or Michel's solutions.
Here's my variation:
.put for [\~] '/A/B/C'
Hi Marc (and Bruce)!
Okay, I use our old friend `:exhaustive` adverb below:
~$ echo "/var/log/messages" | raku -ne '.say for m:ex/ ^ ["/"
<.alpha>+:]**?{1..*} /;'
｢/var｣
｢/var/log｣
｢/var/log/messages｣
If you remove the `?` frugal quant-modifier, the output is the same--except
in the reverse

It will be hard to beat the brevity of a language with single-character
instructions.

hello people,
I have this steps() function implemented this way in shell:
steps() sed -r ':b p; s,/[^/]+$,,; t b'
# demo:
<<. steps | xargs ls -lUd
/var/log/messages
which shows
-rw-r- 1 root adm 464304 Sep 3 19:03 /var/log/messages
drwxr-xr-x 22 root root 4096 Sep 3 00:00 /var/log
11 matches
