I see, thanks for the time you took explaining this. I think it is more a cultural difference then in how patterns evolved.

Your second paragraph was considered a feature in the context of the time

Not a rust dev, rather c++, but just to understand, how should a type be named if it is used to carry information about an error?

Os this an issue with the language, similar to C where you don’t have namespaces, and thus need to call everything acmecorp_error_v5 or something like that?
