+Product: Mono: Compilers
+Version: 1.1
+OS Details: Debian unstable
+Status: NEW

+Summary: Bad error message for unimplementable interface
+The attached program fails on the compilation of the class M. I *know* I am
+doing something really bad but the error is a bit misleading. First of all
+the compiler probably knows that it will be impossible to implement
+interface B<T> but it simply goes on instead of printing an error (or even
+a warning). Then the compilation fails saying to A.X is not implemented
+(true) but does not say that implementing A.X is impossible because of
+B<T>.X already implemented.
+A better error message (maybe a compilation failure on the interface) would
+be a nice addition, IMHO.
