+#7770 ICE with sibling methods containing same-name-enum containing
+ same-name-member
+
+If you have two methods in an impl block, each containing an enum
+(with the same name), each containing at least one value with the same
+name, rustc gives the same LLVM symbol for the two of them and fails,
+as it does not include the method name in the symbol name.
