During the 2022 Perl Advent, in particular the entry for December 06; Perl Advent fans were introduced to a little module called
A lot has already been said about
Util::H2O, and this author uses it a lot in client and production code because it helps produce very clean and maintainable
HASH reference heavy code. So much so, that he created the
Util::H2O::More module to encapsulate some common tasks and additional capabilities for working between pure Perl data structures and blessed objects that have real data accessors, in a natural and idiomatic way.
Support for Generic Perl Data Structures
h2o is perfect for dealing with data structures that are made up of strictly
HASH references, but it is often the case that useful data structures contain a mix of
ARRAY references. For example, when using databases or web API calls returning
JSON, it is often a list of records that is returned. This was the case of the example call that was in the December 06 Perl Advent 2022 article.
I created a very basic calculator using wxGlade and the Wx Perl module on CPAN.
I've had https://github.com/Perl-OpenMP
up for a while, but I only recently thought to post an open invitation for others interested in this exploration topic to join.

My confidence in the value of this line of work was bolstered recently when I shoved in an old finite element of 2dheat conduction into a Perl script using,
is an incredibly powerful tool for managing
references in a more natural way.
This post is the first of several that will explore this awesome module. I've started using it quite a bit in both new code and in existing code. There are several imporant cases where it really shines. Here we explore the power it has to iteratively refine existing code. It's also fun
to introduce into existing code.
