After reading Uri's post about projects for beginners, I took a quick
look at File::Slurp source code, and I was stuck at the very beginning.
My knowledge of Perl is still very beginner level, but I want - time
allowing - to improve as I like the language very much.
Anyway, the code starts with

looking at my code is a good way to learn perl! :)

I *know* about the symbol table and typeglobs, but I yet have to
*understand* how it all works, and how to use it.
My first question here - before everything else

MR Hm no maybe I didn't explain myself: my doubt was not about the

Ah, use constant is just sugar for what he is doing. And, given that

the strange way is because that is how perl does it. perl doesn't have a
proper macro mechanism which is how many langs do constants. so it needs
something that is parsed in perl and subs with empty prototypes work
well.
