+// Expressing the Transferable typedef in IDL depends on http://crbug.com/240176.
+// The postMessage() methods taking a Transferable array argument have custom
+// binding code that is able to handle the Transferables that we currently
+// recognize. To be able to declare a postMessage() signature that matches
+// the implementation, we provide a Transferable typedef but with an
+// incomplete type.
+//
+// FIXME: make this typedef accurate once enough of http://crbug.com/240176
+// is in place.
+// FIXME: consider putting this typedef in an .idl file containing spec-wide
+// utility type definitions.
