Couple of years back I got a PR at work that used a block of code that read a CSV, used some stream method to covert it to binary to then feed it to pandas to make a dataframe. I don't remember the exact steps it did, but was just crazy when pd.read_csv existed.

On a hunch I pasted the code in google and found an exact match on overflow for a very weird use case on very early pandas.

I'm lucky and if people send obvious shit at work I can just cc their manager, but I fell for the volunteers at large FOSS projects, or even paid employees.
