-// 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.
