Description
This is a re-opening of #32777.
Explanations
Those error codes and their explanations are declared in files named error_codes.rs. In those files, you can see generally two macros: register_diagnostics and register_long_diagnostics. If an error code is in register_diagnostics, it means it lacks long error explanation. The goal of this issue is to add those missing explanations!
This is an easy first issue but don't hesitate to ask for help if you're stuck on something!
Here is the list of all error codes that don't have a long error explanation yet:
- E0183 (add long explanation for E0183 #89885)
