Hellow fellow monks.
My question may seem rather simple but I haven't found the anwser either in perl documentation and the super search.
Here is my problem, I have a bigger script wich let's say uses 3 different modules, these 3 modules are only used in some subrutines so we can assume:
Module1, Module2, Module3
sub1, sub2, sub3
The sub 1 uses only Module1 and Module1 is not used anywhere else in the script, the equivalent is for sub2 and sub3. Now my question is of this nature:
Where should I include my modules? If I put the use Module1; use Module2; use Module3; on top of my script I assume that it will be loaded for the whole script witch is not what I want becouse it is only used in some subrutines, not the whole script. I was thinking about puting use Module1; inside sub1 code blocks but three questions came to me as I pondered about it.
Question 1, will the module be loaded for the whole script or just this sub?
Question 2, will the module be loaded each time I call the sub, or maybe just once on startup, or will it be loaded only once when I first time call the sub?
Question 3, if I i put use Module1; inside the subrutines code blocks, will the module be unloaded when the subrutine ends?

Thank you for the time you all sacrificed to read this node ( or maybe even anwser it ;) ) and I hope that none of you will be offended by such a simple question ( well simple for you beacouse my mind seems rather confused by this case ;) ).
