Not really. In each case, the REPL lets you interactively execute code
as part of a module. If you start with "-i somescript.py", it starts
out by running the contents of that script; otherwise, you start with
nothing (as if you ran "-i empty-file.py"). The REPL does the same
thing every time; it's a difference between creating the functions
directly and importing them.
