suggestions for functional style (singleton pattern?)

[yves at zioup.com]

Hi,

For some scripts, I write in a a more functional way, using a lot of small
functions outside of any class. Although it makes the code clearer for
specific cases, I have found that it makes debugging and using the repl in
general difficult, as as I have to re-initialise every single objects every time.

I have now started to use some kind of state pattern to alleviate this, here's
a simplistic example:

Are there better ways to address this? Any suggestion on this style?

Thanks.
