Yes, I'm doing that a lot, too. I'm often astounded how hostile some languages are to later changes - e.g. java always feels resistant to change, while dotnet and especially python are more amenable. I.e. I totally transformed a program from function to oo in python without much sweat - would have been a total pain in dotnet or java

Can you give examples for what you changed?

Basically, my predecessor hat build a python program which had N modules which where applied to a data structure - maybe think of correction steps. First spell checking, than turn manual headlines into actual headlines etc. Originally, they operated on a global data structure, and every new module required calling it on the global structure, so extension was difficult. Worse, every module hat internal state, e.g. the number of spelling mistakes. Reporting these things at the end was cumbersome. There where "required" functions in each module, but it was difficult to newcomers to discover who they where. We changed it so that every step was a class which inherited from a base class, so adding a new step was as easy as inheriting from the base class. Furthermore, we added Auto discovery, so just adding the class in a module was sufficient to get it executed.
