I think everyone else has covered the use vs require.

One benefit to them adding use statements is in an environment such as mod_perl or another environment where alot of processes are forked from a parent. In this case, if you load the modules in the parent process process, the memory can be shared among the children using the OS's copy-on-write abilities.
