Subject: [Purdue-pm] This has to be a thing in sed or something that I
 just didn't know, right?

Thanks for that.

I hit the point where it was simpler for me to write the thing than 
continue to wonder "Can grep do that? awk? sed? Something else?"

But good to know that yes, it's in there.

Subject: [Purdue-pm] Perl 6
Message-ID: <6832.1536672231@pier.ecn.purdue.edu>

A good Perl 6 Resources web page is at
    https://perl6.org/resources

A good summary of Camel, Hungarian, Kebab, and Snake variable naming
conventions is at
    http://www.wellho.net/mouth/4611_Hungarian-Camel-Snake-and-Kebab-variable-naming-conventions.html

Perl 6 allows kebab case variables like $number-of-people (get it?,
shish kebab), which for me is much easier to type and read than the
snake case $number_of_people.  (I started using kebab case when taking a
COBOL class at Purdue in the late 1970s and developed a fondness for it
then.)  In real life I'd name this $np if the program where just about
people or $npeople if the program had more than one variable name that
started with "p".  A long time ago I started using camel case for names
of subs I write like Cos, ArcCos, and ReverseColorMap.  The bigger a
program is the longer I like to make variable names.  And if others will
be looking at the program I am more likely to use longer variable name.

From http://sixfix.nigelhamilton.com
    SixFix is a weekly email with something new to learn about Perl 6. But
    there's a catch! Each email includes a coding challenge and a question
    about Perl 6 you must answer to receive your next SixFix.  I've only
    done the first exercise but I recommend it.

Perl 6 is Perl 5 redesigned and rewritten from the ground up but it
still feels like programming in Perl 5.  In my opinion, Perl 6 is a much
better language than Perl 5---Perl 5 is more mature now but if Perl 6 has
all the packages you need I suggest you start using it to get familar
with it.

An easy-to-read, description of "How subroutine signatures work in Perl
6" for beginners is available at
    https://opensource.com/article/18/9/signatures-perl-6

It's easy to read, not too long, and covers basic knowledge one needs to
define their own Perl 6 subroutines.

For me, the best way to learn Perl 6 has been by reading articles like
the above.  The knowledge is bite-sized, gives you enough to do simple
things, but doesn't cover all the material a reference manual does.
Perl 6 is powerful---it is hard to try and learn everything at once.
