perl module loads the script specified by filename parameter in mod 
init. It parses it in the interpreter and then you can execute perl 
functions from inside the script at runtime.

So, it is not loading it every time a function is executed. There is 
some code to be able to reload, but afaik, feature was not finished.

Regarding lua, there are couple of functions, some of them allowing to 
execute parts of a file loaded at startup, other will load the script 
every time.

Cheers,
Daniel
