Fellow monks,

I have a set of configuration variables that I run when I first start my application, like this: 

my $vars = &load_vars();

[download]


The sub loads a text file containing the configuration values (in key/value pairs), and returns a hashref.

What I did this far was to pass this hashref around to just about every sub in my app. So, to create a database connection: 

my $dbh = &init_db($vars)

[download]


And so on and so forth. Many subs later, I'm thinking that there might be a better way to implement this. I don't want to invoke the &load_vars sub all the time, as it reads from disk, so basically, is there any way to make that hashref persistant across the entire application, without having to pass it around?

Appreciate your input on this...

cheers,
Alex.
