"""
Lisp languages support an image-based development cycle at the REPL.

R - having its roots in Lisp - it was first implemented in Scheme - has overtaken this.
R's base command `save.image(filepath)` can save the state of an entire REPL session in a file,
and next time you start R, you can start where you stopped, by hitting `load(filepath)`.

I was asking myself, since Python's REPL is ipython, what supports 
similar functionailities for pythonistas.
