+Thanks for the bug report. The bug was simple, we were not handling
+the "U operator - (E x, E y)". The semantics are interesting, but not
+that complex. The rationale seems to be that it is valid to compute
+the difference between enumeration values, but it is not valid to
+return an enum value by addition.
+All the errors and those cases are now handled by the compiler.
