sorting

[Skaperen]

in another project i ran into this issue with str vs int. but i can see potential cases where other types could be there, hence the the thought of using repr(). but i am not sure if that is even good enough. i wonder if json.dump() can handle all possible types or if pickle would be a better choice. oh wait, there are cases where even pickle can fail. the only final answer i can think of is to do try: and if there is an exception just use some fixed string like '?'.
