@ChristosArgyrop@mstdn.science Very detailed description. I've used Perl for years and didn't know all that about it. Even so it's been my go to language for decades. I generally use the PDL as data analysis was one of my main interests. For graphics I generally used the TriD 3D package and the PGPLOT package, as well as calls to the always available GNUPLOT utility. The flexibility of expression meant a lot to me, as I was also a Forth user.
