Load modules and create objects on demand
Certain applications like to defer the decision to use a particular module till runtime. This is possible in perl, and is a useful trick in situations where the type of data is not known at compile time and the application doesn’t wish to pre-compile modules to handle all types of data it can work with. Loading modules at runtime can also provide flexible interfaces for perl modules. Modules can let the programmer decide what modules will be used by it instead of hard-coding their names.
