use require and loading modules

[buildmorelines]

As I understand, if I load a module with "use" it will be parsed
imidiatly on/read during compiled/eats up initial start-up time, if I
use "require" it is loaded when perl reaches the require statement?

I am trying to load a module, but I want to save time on start up, so
I want to load the module much later on in the program, and its not
always required.

?? Then change your code, for god's sake.

I didnt have enough cola

What I was asking is, is there any way to load modules after the
initial compilation, as needed/on the fly/dynamically, so I wont be
loading code that will not get used?

As I understood, if I uses "use" to do it, the module will be parsed
and compiled when the program is run for the first time. I dont want
the module to be parsed and compiled when the program is run for the
first time, I want the module to be paresed and compiled when I say
its ok. how would I do this in Perl?

require MyModule;

does just that, i.e. the module gets loaded only if and when that
statement is executed.

require MyModule;

does just that, i.e. the module gets loaded only if and when that
statement is executed.

See perldoc perlmod.

use MyModule;

is equivalent to

BEGIN{ require MyModule; import MyModule; }

and

use MyModule @LIST;

is

BEGIN{ require MyModule; import MyModule @LIST; }

I think the OP is really looking for autouse.
