Devel::REPL is a module for creating Read-Evaluate-Print-Loops (REPL) in
 Perl. The shell provides for rapid development or testing of code without the
 need to create a temporary source code file.

 Through a plugin system, many features are available on demand. You can also
 tailor the environment through the use of profiles and run control files, for
 example to pre-load certain Perl modules when working on a particular
 project.
