In my opinion Raku is a much better tool than Perl 5.
Just like Mathematica is a much better tool than MATLAB.

Dear Mark,

Mathematica and MATLAB are apples and oranges.

Mathematica and Maple are much better for symbolic computing than 
MATLAB, but I think MATLAB is much, much better suited than either of 
these for numerical computation, i.e., for numerical work with pde's, 
computing on a mesh, etc.? These are totally different types of tools.? 
As different as a saw versus a hammer.

It seems like Raku and Perl 5 are shaping up to be pretty different 
tools too, right?? Perhaps much more similar to each other than 
Mathematica and MATLAB.

Mark

I no longer use MATLAB.  Everything I did in MATLAB I now do in
Mathematica.  It seems to work fine for me for everything I've tried.
Mathematica was much harder to learn than MATLAB but the payoff has been
much bigger.  I wish Mathematica had LaTeX-based notebooks though.  I
really like all the data conveniently available from Mathematica, see
https://datarepository.wolframcloud.com
for more info on that.

Raku and Perl 5 do basically the same tasks in my opinion---Perl 5 has a
lot more authors and modules in CPAN (Comprehensive Perl Archive
Network) than is currently available for Raku.  Raku has everything I
need now plus some stuff I don't use now but doesn't get in the way
because it doesn't conflict with what I do use.  One big feature of Raku
that is not built-in to Perl 5 is grammars (see
https://docs.raku.org/language/grammars).  I've done a very simple test
using those but expect to use them for real work later.  My guess is
that will greatly reduce the amount of work I need to do.

In short I'd characterize the problems that can be solved using MATLAB
as a subset of what can be done in Mathematica.  I haven't done
benchmarks to see which is faster.  Same for Perl 5 and Raku.  Raku has
lots of odd things that were in Perl 5 fixed.  Raku has invariant
sigils.  For example in Perl 5, @array is an array and $array[1] is the
second element of @array.  In Raku, @array is an array and @array[1] is
the second element of @array.  A lot of things are easier in Raku,
it has more and more flexible syntax.

Subject: [Purdue-pm] On Perl 7 and the Perl Steering Committee
Message-ID: <17766.1597072686@pier.ecn.purdue.edu>

The "On Perl 7 and the Perl Steering Committee" document
starts with
    For those who are wondering about the state of the
    proposed Perl 7 fork and the role of the newly formed
    Perl Steering Committee, Ricardo Signes has put together
    a detailed explanation that is worth a read.
For the complete Perl 7 document see
    https://lwn.net/Articles/828384

Remember: Perl 7 is planned to based on Perl 5.  Perl 6 was
designed and written from scratch and is now known as Raku.
Programming in Raku "feels like" programming in Perl 5 or
Perl 7.  I like Raku much better than Perl 5 or Perl 7.
