IMHO, this seems really complex. That JSON configuration looks really
scary to me and sadly I don't think I could bring myself to use this.
Fundamentally the need you are addressing is that you want to manipulate a
text file and leverage Stellar as part of that pipeline, right?
In a perfect world, I'd be able to use Unix-y tools like Grep, Sed, Awk,
etc and introduce Stellar expressions as part of the pipeline. I know it is
already possible to some degree with the REPL.
I am wondering if with a little brainstorming we might be able to arrive at
a simpler solution that allows us to leverage tried-and-true UNIX pipelines so
that people can use the Unix-y tools they are familiar with. I feel we'll get
better user traction with a simpler, more familiar approach.
