+reflection-names-neg.scala:5: error: type mismatch;
+ found   : String("abc")
+ required: reflect.runtime.universe.Name
+Note that implicit conversions are not applicable because they are ambiguous:
+ both method stringToTermName in trait Names of type (s: String)reflect.runtime.universe.TermName
+ and method stringToTypeName in trait Names of type (s: String)reflect.runtime.universe.TypeName
+ are possible conversion functions from String("abc") to reflect.runtime.universe.Name
