Some of my (primarily CGI) scripts have subroutines that rarely get called. Things like error handling which (hopefully) never get run but which need to be there in case something unexpected happens.

Sometimes these infrequently used routines need to load a module or two. I'd just as soon not have to load these modules into memory every time the script runs unless I need to. So, I've begun using require and import rather than always using use.

My question is whether there are any real drawbacks to this, other than having to explictly import the features I want from the required module? Am I really saving any system resources, or am I just wasting time by typing that extra line of code?
