For the following bad code --- enum E : ubyte { e0, e1, e3, e4 } void main() { switch (node.e) { case E.e0: return; case E.e1: return; default: return; } } --- DMD reports: > /tmp/temp_7FAD2C00A670.d:10:13: Error: undefined identifier `node` > /tmp/temp_7FAD2C00A670.d:13:9: Error: duplicate `case e1` in `switch` statement The first error message is correct. The second error message is a bad diagnostic.

According to the compilers available on run.dlan this wouldbe a 2.094 regression. (https://run.dlang.io/is/Svfzoy)
