Unexpected compiler exception EXCEPTION


I was wondering what this error meant while creating a case in a visit statement?enter image description here

This is an example of the case causing it:

case (Statement) `<Lifetime lt>: <Statement stmt>` => (Statement) `<Statement stmt>`

My goal with this is just to delete the Lifetime statement together with the following colon.


Solution

  • Thank you for reporting this and many apologies for this brutal and incomprehensible message. The error means that there is a parse error in one of the concrete fragments between ` and `.

    We will improve the reporting of this kind of errors!
