Question

from perldoc -f use
syntax of the function use:

   use Module VERSION LIST
   use Module VERSION
   use Module LIST
   use Module
   use VERSION

but in this case:

use Test::More tests => 5;

(it sets number of tests to 5)

What is data type of the expresion tests => 5?
Is it LIST or something else?

How can I use this parameter tests after declaration?

Answer 1

Yes, it’s the LIST mentioned – the => is just a fancy way of writing this:

use Test::More ("tests", 5);

Which in turn calls Test::More->import("tests", 5) after loading the module.
