Dear Larry,
Thank you so much for such a complete reply!
Not to keep score here, it seems like 9/10 Perl5 'one-liner tricks'
are baked into Raku from the language's inception. [ The only feature
that might be missing is 'Trick #3' where Perl5 modifies a file
in-place at the bash command line
Try it with a very filled folder, though. I would expect the majority of
the time spent is setup and actually going through the lines themselves
isn't very slow.

Larry,
good to see you here!
Of course, I have some comments on your suggestions :-)

That is a little bit disappointing:
$ time ls -l | perl -lane 'print "$F[7] $F[1]"' > /dev/null
real 0m0.008s
user 0m0.013s
sys 0m0.000s
$ time ls -l | raku -ne 'say "$_[7] $_[1]" given .words' > /dev/null
Use of Nil in string context
in block at -e line 1
real 0m0.302s
user 0m0.370s
sys
