I wouldn't worry about it too much. As far as I can see, the time it
takes to compile all of the code should be almost constant.

Lets say you have a 50 line script that "require"s a 25 line library.
If you cut and pasted the library inline at the top of the script,
perl would compile all 75 lines and then start executing the its
internal representation of the code. If you kept the library as a
separate file, perl would comple 50 lines, start executing any
statements before the "require" statement, and then compile 25 lines.
