I am ok with this, but this is going to create a hell of a lot of cycles, so I prefer to manually delete the list with all the exceptions once error_msgs is done to alleviate this a bit.

I actually thought about the reference cycle problem -- that's why these are strings and not exception objects -- I don't think there's actually any cycles added by this PR ? unless you're hinting at something I don't know about!

Oh, my bad, I was reading this as keeping the errors in the list instead of the string representation. Maybe renaming errors to error_messages? If you prefer not to do that is fine, I think we can go as it is as well.

ah yeah that would be better -- but then what to call the joined variable 🤔 (to avoid having a variable change type)

the joined variable
final_error_msg ?

Notice that even if it contains the summary of multiple error messages is a single error message at the end.
Maybe you can call it summary_error_msg?

went with error_msgs and error_msgs_summary -- thanks for the suggestion!
