 [error] Couldn't infer type parameter 'T'.
 
-Inferred type '_ControllerEventSinkWrapper<dynamic>' does not work with constraints:
-  Argument 'action' inferred as '(EventSink<T>) → dynamic' must be a '(T) → R'.
+Tried to infer '_ControllerEventSinkWrapper<dynamic>' for 'T' which doesn't work:
+  Parameter 'action' declared as     '(T) → R'
+                     but argument is '(EventSink<T>) → dynamic'.
 The type '_ControllerEventSinkWrapper<dynamic>' was inferred from:
-  Argument 'argument' inferred as '_ControllerEventSinkWrapper<dynamic>' must be a 'T'.
+  Parameter 'argument' declared as     'T'
+                       but argument is '_ControllerEventSinkWrapper<dynamic>'.
 
 Consider passing explicit type argument(s) to the generic.
