I believe the first step would be to show that which combination of current_exception + messages should be split into various new exceptions. To give a possible concrete example, if you have a look at https://aroberge.github.io/friendly-traceback-docs/docs/html/tracebacks_en_3.6.html, you will see that TypeError can have various messages such as: * must be X not Y (where X might be str and Y might be list, etc.) * can only concatenate X (not Y) to X * unsupported operand type(s) X for: Y and Z * X not supported between instances of Y and Z * bad operand type for unary X: Y * X object does not support item assignment * X takes Y positional arguments but Z was given * X missing 2 required positional arguments: Y and Z * X object is not callable There are likely many more cases only for TypeError (not to mention other types of errors.) Note that there are actual tests for each of these (which is one important criterion as mentioned by Serhly). (This comment does not mean that I am not necessarily expressing support for adding many new exception types.) You're welcome to start collaborating and help document all possible cases. This invitation to collaborate is, of course open to all.
