Maybe I got it all wrong. I started working with objects but perhaps it's not necessary and I'm just over-complicating things.

So let me describe the scenario (I probably should have asked for your advice about it earlier)

My perl script is used to run some kind of a pipeline. I start by reading a JSON file with a bunch of parameters in it. I then do some work - mainly building some data structures needed later and calling external programs that generate some output files I keep references to.

I usually use a subroutine for each of these steps. Each such subroutine will usually write some data to a unique place that no other subroutine writes to (i.e. a specific key in a hash) and reads data that other subroutines may have generated (when I sued an object I had a large $self with many keys).

These steps can take a good couple of minutes if done sequentially, but most of them can be run in parallel with some simple logic of dependencies that I have described in an earlier post and I now know how to handle.

What would you suggest? perhaps a simple script (no objects) with "global" shared variables?

Thank you
