Yes, +1 and we have this documented on the py-to-perl6 nutshell page:

Hello folks. Did I understand correctly that this thread is about list
comprehension syntax in Perl 6? :-)
I don't if it was mentioned, but I think this syntax just simply works
already. See an example:
> say ($_~$_ if $_ %% 2 for ^10).Set
set(00 22 44 66 88)
> say ($_.item if $_

Ups :O .Thanks for the conceptual clarification. :D I will leave P
Actually I would suggest NOT adding Perl6, because the best way to
create a Set is not to use “list comprehension”, but to just call
`.Set`
That whole page is about Set Builder Notation, but Perl6 doesn't
actually have such a thing.
You create a Set through a method call, or a subroutine call
Dear Brad,
Thanks very much for the answer. I have been playing with your examples in the
code below (and learned a lot!). Based on your insight, I would suggest these
solutions to be added to the wikipedia:
https://en.wikipedia.org/wiki/Set-builder_notation#Parallels_in_programming_languages
In
{l for l in L}
The reason it is in `{}` is to create a Set from iterating over `L`.

So in Python:
[ l for l in L ]
Hi all,
I wonder what would be the Perl notation for 'set-builders', as exposed
in this wikipedia article:
https://en.wikipedia.org/wiki/Set-builder_notation#Parallels_in_programming_languages
This is the Python notation:
Example 1: {l for l in L}
Example 2: {(k, x) for k in K for x in X
